Yes, if you believe in the Pangaea theory, the idea that Earth's continents were once part of a single landmass called Pangaea, which broke apart to form the continents we know today: 

This can explain why the oldest human-made structure in the Americas is older than the Egyptian pyramids. 

To find the oldest known human-made structures in the Americas, you don't need to hike into the wilderness or paddle down a raging river — all you need to do is visit Baton Rouge, Louisiana. 

At the north end of Louisiana State University's (LSU) campus sit two grassy mounds, rising in a gentle slope to a height of about 20 feet (6 meters). The mounds are just two of more than 800 similar human-made mounds in Louisiana, built by Indigenous Americans. Although researchers knew they were old, a new study has determined just how old these ancient structures are. 

The grassy surface hides layers of ancient clay, dirt and ash. And researchers recently found that the oldest mound is 11,000 years old, making it the oldest human-made structure discovered in either North or South America. 

There's nothing known that is man-made and this old still in existence today in the Americas, except the mounds," study first author Brooks Ellwood, emeritus professor of geology and at LSU, said in a university statement. The research was published in the June issue of Yale University's American Journal of Science 

History of the mounds 

For the study, the researchers took sediment cores from each of the mounds to determine their age. In these cores, the researchers found layers of clay and ash from burned reed and cane plants, as well as microscopic animal bone fragments. 

Because the flames from reed and cane are too hot to cook food with, the researchers think that the mounds were built up and used for religious or ceremonial purposes. 

The two mounds aren't the same age. Mound B, which lies to the south of Mound A, is the oldest of the two. Using radiocarbon dating, which measures how much of the radioactive isotope carbon-14 has decayed in organic matter, the researchers determined that Mound B is 11,000 years old, while Mound A is around 7,500 years old. The finding reveals that both mounds are older than the ancient Egyptian pyramids; the oldest pyramid, the Step Pyramid of Djoser, was constructed at Saqqara about 4,700 years ago. 

By studying the cores and the surrounding landscape, the researchers built a general timeline for the mounds' construction. A large depression in the ground near LSU's Hill Memorial Library hinted that Mound B was probably constructed from material in that area starting around 11,000 years ago. Over thousands of years, ancient humans continued to build up the mound with clay and by burning plants and animals on the mound. 

Then, around 8,200 years ago, Mound B was abandoned — and researchers aren't sure why. But a rapidly changing climate could have had an impact. Starting around 8,200 years ago, temperatures in the Northern Hemisphere suddenly dropped around 35 degrees Fahrenheit (19.4 degrees Celsius), for reasons unknown, and stayed that way for about 160 years, according to the statement. 

"We don't know why they abandoned the mounds around 8,200 years ago, but we do know their environment changed suddenly and dramatically, which may have affected many aspects of their daily life," Ellwood said. 

The team found no evidence of human activity at Mound B for the next 1,000 years. Then, around 7,500 years ago, ancient people started constructing Mound A about 30 feet (9 m) away, using mud from a floodplain where today's LSU Tiger Stadium now sits. 

The researchers also discovered a stellar characteristic of the mounds — they line up just 8.5 degrees east of north, which is where the giant red star Arcturus would have risen several thousand years ago, according to LSU astronomers. Around 6,000 years ago, both mounds were completed to align toward Arcturus. The university is now moving to help preserve these ancient monuments. Over the years, researchers have encouraged students and visitors to avoid walking or sitting on the mounds. Although their grassy slopes seem inviting for a picnic or study break, the structures were clearly important to the Indigenous Americans who populated the area. LSU is planning to protect the mounds by building a path and a buffer zone of native plants, so visitors can view the ancient structures without damaging them. 

Gopher Wood: 

Gopher wood is a term that appears only once in the Bible, in Genesis 6:14, where God instructs Noah to build the Ark out of it. The word gopher is not used anywhere else in the Bible or the Hebrew language. 

Note: Gopher wood," also known as the Torreya tree (specifically "Torreya taxifolia"), can only be found in Florida, more precisely in a very limited area along the Apalachicola River in the northern part of the state, bordering southwestern Georgia; making it a highly endangered and rare species. 

Atlantis Could Equal Americas. The ancient cities of Egypt. 

The Americas: 

The Americas are surrounded by the Atlantic Ocean on the east coast and the Pacific Ocean on the west coast, with the Arctic Ocean bordering the northern parts of North America; essentially, the Americas are surrounded by sea on all sides. 
 

Atlantis Theory: 

Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, romanized: Atlantìs nêsos, lit. 'island of Atlas') is a fictional island mentioned in Plato's works Timaeus and Critias as part of an allegory on the hubris of nations. In the story, Atlantis is described as a naval empire that ruled all Western parts of the known world, making it the literary counter-image of the Achaemenid Empire. After an ill-fated attempt to conquer "Ancient Athens," Atlantis falls out of favor with the deities and submerges into the Atlantic Ocean. Since Plato describes Athens as resembling his ideal state in the Republic, the Atlantis story is meant to bear witness to the superiority of his concept of a state. 

Despite its minor importance in Plato's work, the Atlantis story has had a considerable impact on literature. The allegorical aspect of Atlantis was taken up in utopian works of several Renaissance writers, such as Francis Bacon's New Atlantis and Thomas More's Utopia. On the other hand, nineteenth-century amateur scholars misinterpreted Plato's narrative as historical tradition, most famously Ignatius L. Donnelly in his Atlantis: The Antediluvian World. Plato's vague indications of the time of the events (more than 9,000 years before his time) and the alleged location of Atlantis ("beyond the Pillars of Hercules") gave rise to much pseudoscientific speculation. As a consequence, Atlantis has become a byword for any and all supposed advanced prehistoric lost civilizations and continues to inspire contemporary fiction, from comic books to films. 

While present-day philologists and classicists agree on the story's fictional nature, there is still debate on what served as its inspiration. Plato is known to have freely borrowed some of his allegories and metaphors from older traditions, as he did with the story of Gyges. This led a number of scholars to suggest possible inspiration of Atlantis from Egyptian records of the Thera eruption, the Sea Peoples invasion, or the Trojan War. Others have rejected this chain of tradition as implausible and insist that Plato created an entirely fictional account, drawing loose inspiration from contemporary events such as the failed Athenian invasion of Sicily in 415–413 BC or the destruction of Helike in 373 BC. 

The Moors enslaved Christians and other non-Muslims in al-Andalus, or Islamic Iberia. The Moors also imported white Christian slaves from Eastern Europe and Spain. 

If the term “Moor” seems familiar but confusing, there’s a reason. Though the term can be found throughout literature, art, and history books, it does not actually describe a specific ethnicity or race. Instead, the concept of Moors has been used to describe alternatively the reign of Muslims in Spain, Europeans of African descent, and others for centuries. 

Derived from the Latin word “Maurus,” the term was originally used to describe Berbers and ethnic groups from the ancient Roman province of Mauretania in what is now North Africa. Over time, it was increasingly applied to Muslims living in Europe. Beginning in the Renaissance, “Moor” and “blackamoor” were also used to describe any person with dark skin. 

In A.D. 711, a group of North African Muslims led by the Berber general, Tariq ibn-Ziyad, captured the Iberian Peninsula (modern Spain and Portugal). Known as al-Andalus, the territory became a prosperous cultural and economic center where education and the arts and sciences flourished. 

Over time, the strength of the Muslim state diminished, creating inroads for Christians who resented Moorish rule. For centuries, Christian groups challenged Muslim territorial dominance in al-Andalus and slowly expanded their territory. This culminated in 1492, when Catholic monarchs Ferdinand II and Isabella I won the Granada War and completed Spain’s conquest of the Iberian Peninsula. Eventually, the Moors were expelled from Spain. 

By then, the idea of Moors had spread across Western Europe. “Moor” came to mean anyone who was Muslim or had dark skin; occasionally, Europeans would distinguish between “blackamoors” and “white Moors.” 

One of the most famous mentions of Moors is in Shakespeare’s play The Tragedy of Othello, the Moor of Venice. Its titular character is a Moor who serves as a general in the Venetian army. (In Shakespeare’s time, the port city of Venice was ethnically diverse, and the Moors represented a growing interchange between Europe, the Middle East, Asia and Africa.) Despite his military prowess, Othello is also portrayed as exotic, hypersexual, and untrustworthy—“a lascivious Moor” who secretly marries a white woman—reflecting historic stereotypes of black people. 

More recently, the term has been coopted by the sovereign citizen movement in the United States. Members of Moorish sovereign citizen groups claim they are descended from Moors who predated white settlers in North America, and that they are part of a sovereign nation and not subject to U.S. laws. It’s proof of the ongoing allure of “Moor” as a seemingly legitimate ethnic designation—even though its meaning has never been clear. 

The term Moor is an exonym first used by Christian Europeans to designate the Muslim populations of the Maghreb, al-Andalus (Iberian Peninsula), Sicily and Malta during the Middle Ages. Moors are not a single, distinct or self-defined people. The 1911 Encyclopædia Britannica observed that the term had "no real ethnological value." Europeans of the Middle Ages and the early modern period variously applied the name to Arabs, Berbers, and Muslim Europeans. 

The term has also been used in Europe in a broader sense to refer to Muslims in general, especially those of Arab or Berber descent, whether living in al-Andalus or North Africa. During the colonial era, the Portuguese introduced the names "Ceylon Moors" and "Indian Moors" in South Asia and Sri Lanka, now official ethnic designations on the island nation, and the Bengali Muslims were also called Moors. In the Philippines, the longstanding Muslim community, which predates the arrival of the Spanish, now self-identifies as the "Moro people", an exonym introduced by Spanish colonizers due to their Muslim faith. 

In 711, troops mostly formed by Moors from northern Africa led the Umayyad conquest of Hispania. The Iberian Peninsula then came to be known in Classical Arabic as al-Andalus, which at its peak included most of Septimania and modern-day Spain and Portugal. In 827, the Aghlabid Moors occupied Mazara on Sicily, developing it as a port. They eventually went on to consolidate the rest of the island. Differences in religion and culture led to a centuries-long conflict with the Christian kingdoms of Europe, which tried to reclaim control of Muslim areas; this conflict was referred to as the Reconquista. In 1224, the Muslims were expelled from Sicily to the settlement of Lucera, which was destroyed by European Christians in 1300. The fall of Granada in 1492 marked the end of Muslim rule in Spain, although a Muslim minority persisted until their expulsion in 1609. 

The etymology of the word "Moor" is uncertain, although it can be traced back to the Phoenician term Mahurin, meaning "Westerners". From Mahurin, the ancient Greeks derive Mauro, from which Latin derives Mauri. The word "Moor" is presumably of Phoenician origin. Some sources attribute a Hebrew origin to the word. 

During the classical period, the Romans interacted with, and later conquered, parts of Mauretania, a state that covered modern northern Morocco, western Algeria, and the Spanish cities Ceuta and Melilla. The Berber tribes of the region were noted in the Classics as Mauri, which was subsequently rendered as "Moors" in English and in related variations in other European languages. Mauri (Ancient Greek: Μαῦροι) is recorded as the native name by Strabo in the early 1st century. This appellation was also adopted into Latin, whereas the Greek name for the tribe was Maurusii (Ancient Greek: Μαυρούσιοι). The Moors were also mentioned by Tacitus as having revolted against the Roman Empire in 24 AD. 

During the Latin Middle Ages, Mauri was used to refer to Berbers and Arabs in the coastal regions of Northwest Africa. The 16th century scholar Leo Africanus (c. 1494–1554) identified the Moors (Mauri) as the native Berber inhabitants of the former Roman Africa Province (Roman Africans).
