Even though we’d all like to know that we’ve seen all that we need to see on Earth, there are always mysteries being discovered by scientists- like this 6,000-year-old underwater civilization that could change everything we know about the area’s history.

A team of researchers think they have discovered an ancient city that would completely rewrite human history.

We’ve seen a lot of lost cities be discovered, just like this one that hasn’t been touched in 25 years due to arguments between scientists.

It all began in 2001 when marine engineer Paulina Zelitsky and her husband, Paul Weinzweig, from Advanced Digital Communications (ADC), claimed to have found stone structures near Cuba, at around 2,000 feet under the water’s surface.

Sonar technology confirmed that what they had seen was what appeared to be sunken pyramids, circular stones and what appeared to be buildings that could amount to a lost city in the Caribbean waters.

“It's a really wonderful structure which really looks like it could have been a large urban center,” Zelitsky said as per the Daily Mail.

This forgotten city was thought to be 6,000 years old, which could change everything we know about history and civilization.

This is because it would be older than the Egyptian pyramids and other major wonders of the world and notable events that would edit what we know about humanity’s development on Earth.

But for some reason, nobody has been back to investigate the underwater structure.

This is because other scientists believe it could be naturally formed rocks, instead of a man-made city.

Others say that in order for it to have sank so far below the surface, it would have taken 50,000 years to do so, putting it far behind our history than initially thought.

But when images of the rocks began to do its rounds on social media, people began to chant that this could be the lost city of Atlantis.

However, skeptics could not disagree more than they already do, with Cuban geologist Manuel Iturralde-Vinent of Cuba's Natural History Museum being adamant that it could very well just be a naturally occurring structure formation.

“It would be totally irresponsible to say what it was before we have evidence,” Zelitsky echoed in a 2001 interview with BBC.

Michael Faught, a specialist in underwater archaeology at Florida State University, also shared his doubts that these structures were man-made.

“It would be cool if Zelitsky and Weinzweig were right, but it would be really advanced for anything we would see in the New World for that time frame. The structures are out of time and out of place,” said Michael Faught, a specialist in underwater archaeology at Florida State University to the South Florida Sun-Sentinel.

As no expedition to Cuba's Guanahacabibes Peninsula have taken place, it’s hard to refute this belief that the stones happened to be formed by environmental materials.

In 2002, Iturralde said it would be impossible for the ruins to sink nearly half a mile because of shifting tectonic plates, and if it did in fact take the roughly 50,000 years to reach the sea floor, it would change everything we know about humans.

50,000 years ago, it is believed that Homo sapiens were hunter-gatherers without the ability to create civilizations, let along massive and intricate pyramid structures.

“It's strange, it's weird; we've never seen something like this before, and we don't have an explanation for it,” Iturralde told The Washington Post.
