Yonaguni is considered a man made structure, or at the very least carved and manipulated by humans. Even by the scientists. Dr. Kimura is considered an authority in the areas of history and geology.

The giant turtle image facing certain constelations is pretty convincing.

Learning in a specific field, in like a school, and then becoming a researcher in a specific field, is never going to gain you the knowledge and experience of someone like graham hancock. You would never find correlations between different cultures because you only understand one to a good degree.
Why do archaeologists ignore the possiblity of underwater archaeology so much? Probably because it doesn't fit with there narrow understanding of history. THere are huge amounts of now-submerged land, and what we don't know is way, way greater than what we do know of history.
But with real experience all over the world, you can discover and know things others won't be able to. Gain knowledge and expertise that no conventional "scientist" can. You may take comfort in your double blin studies and peer review, but they are only tools for a certain purpose, they can't gain you experience or make you knowledgable like someone like Mr. Hancock.
Graham Hancock has raised many issues ignored by conventional scientists. He has done a good job of challenging the commonly held beliefs, and has withstood and answered scrutiny. You can't just claim his work has no basis, it definitley does.
I remember a show where he showed that the bimini road blocks, are all raised above the sea floor about 6 inches, by almost cone shaped( but stable, not pointed on the end) pillars at each corner. That doesn't look natural. He pointed out that the geologists who claimed it was natural did not even probably look underneath the blocks, or completely ignored that part.
Another issue I read brought up here is where did the prehistoic monument building knowledge go? Is it not possible the people are all gone now? Or are all dead now? If not, in like 10,000 years a lot of things are going to just simply disappear, or perhaps be only known in a few small traditions.
We know ancient cultures were very concerned with Feng Shui and astronomy, Grahan Hancock I'm sure is correct in his theories, as they are quite detailed and clearly documented with evidence, and the fact I just said, Feng Shui is a big part of ancient knowledge in many cultures.
