Of the first ten "proof", seven or eight were based on the fallacy of begging the question. A large structure is described as if it were built on a flat surface and then it is pointed out that this description is incompatible with a curved earth. That doesn't prove anything. You have to prove that it is, in fact, built on a flat surface, not just assume that it is.
