i like the alien theory, just because i firmly believ that aliens built the pyramids based on the mathematical figurations of the sphynx and the surrounding pyramids being equal to that face and surrounding mountains on mars.....but if that is how we were created, how were the aliens created?
or....what if something happened, like the big bang, which created mars with life and earth with life, but based on various factors the evolutionary process on mars aged faster? so, when aliens were off flying around exploring space, our world was field with men clubbing their wives and painting with their feces...
