The structures of Yonaguni, located a few kilometers from the Japanese island of Yonaguni, were discovered in 1997 by the Japanese diver Kihachiro Aratake when he made a dive in the area, he found them by chance!These megalithic structures are formed by huge slabs of stone that form terraces, walls, public roads and even plumbing for drainage! With a length of 300 meters and a width of 150 meters are the largest submerged structures known by archeology. However recent studies have shown that it may be much greater if remove the accumulated debris layer naturally over thousands of years.
The age of its construction is estimated at 11,000 years ago, which was the period of the last glaciation where the sea level would be much lower than the current one. We have more and more evidence that the ancient man was no ignorant who lived only from hunting and gathering, but belonged to an advanced civilization and to some extent exquisite ... Very different from what they tell us in the history books and in the own Universities.
I think the best thing to do is try to rewrite the history books based on recent archaeological studies and discoveries.
College Gentlemen, seriously think about it!
