maybe, stories like these, like ancients metallic bullets found together with animals fossils, or the abundance of pyramids, or the shape itself across ancient cities, from peru to egypt to thailand to indonesia, to the pacific, with just little probability of these civilizations to have been in contact to share this technology.. and the markings in nazca, like launching pads of some craft of some sort.. if there are indeed aliens. this would really cause a breakdown in many ideologies..
