Wilson challenges the evidence presented in Chariots of The Gods. As scary as Chariots was, Crash seems to fall on its face in similar ways. Ad hominems and non-sequiturs abound. At the end, it even goes way off topic to claim the evils of the ancients are the result of Satan operating in the world. So we are to believe it could not have been aliens because it was actually a fallen angel.
Still, of the two, I prefer Crash.
