these monuments/pyramid/temple were found off the coast of japan , they date back to over 4000 years . who built them? are they really natural like they claim? they are i think 2000 years older than the egyptian pyramids. there weren't supposed to be intelligent humans alive at that time, so we must have our history entirely wrong, if they were in fact, man made.
