content: sorry, but if just 1% of what has been found of human made ancient structures are officially contributed to human beings of that time making them. ALL history books has to be revoked together with our entire understanding of human origin.  because that will mean that the silly infentile number of 200,000 years is grossly underestimated. but alas, that would mean that there are a number of professors and academics that will have to conclude that their gathered knowledge thus far is void. and so, overlooking blatant evidence found EVERYWHERE is a lot easier and safer for ones own carreer.
