I was specifically talking about the sitting statues that he said were made of single pieces of stone when they clearly weren't.
As for the toppled colossus if it is the one I think you mean, then I have problems with his claims as well. That being his claim that it was toppled by a heat explosion. We know exactly what happens to any given stone when heated it will either completely melt, partially melt, or metamorphose and you will get almost exact temperature readings off the rocks.
Lastly, he said the earth altered it axial tilt from a straight zero degrees tilt to 23ish degrees. That is absolutely a bullshit statement. The earth alters its axial tilt from roughly 22 degrees to roughly 24 degrees on a 44000 year cycle.
