RikRaeder,
I am sure you have seen pictures of Stone Henge, Pyramids of Giza, Mayan Pyramids, Stone Sculptures on Easter Island. Even these scientifically proven mandmade features don't have perfect right angles like Yonaguni. Yet right angles like what are seen in Yonaguni don't form in nature. Nature has its own order, and it is the opposite of mans order. The opposite of mans order is entropy. For example if you rake up a pile of leaves if you don't constanly re-rake the leaves a gust of wind is going to destroy your order. The same happens in nature, with right angles. I have seen much of the fotage also, but a visit to Yonaguni and seening the photo's of Arataki the original discover of the ruins, it is unequivical that these structures were manmade. The reason that the scientific community does not want to admit that the ruins were manmade it would re-write human history by over 10,000 years. On the discovery channel there was a show about 5 underwater cities (Alexanderia, Egypt; Herodville, Isreal; city in India , Yonaguni, and one in England. What if God did flood the world (in Noah Arc's Day) as it was told in the bible and we are just now discovering these under water ruins? 2/3rds of the world is covered by water, yet more men have walked on the moon than have been to the bottom of the ocean.
