Just some debunking
1. Puma Punku was built by Precolumbian Indians 2000 years ago, not by aliens 14,000 years ago. Only copper and stone tools were found at Puma Punku, not high tech alien tools, and half of the stone blocks at the site are sandstone, not granite as the AA *beep* claim. The site was destroyed not by an asteroid impact as the AA morons claim but by 16th Century Spanish conquistadores looking for gold. The ancient Indians could easily carve, cut, transport, and fit into place those stone blocks at Puma Punku using copper and stone tools and rope.
2. The Palenque sarcophagus lid shows not an alien in his rocket ship but a deceased Mayan ruler (the one whose tomb the sarcophagus lid was found in) falling into the afterlife with a large sacred Mayan tree symbol and other sacred Mayan symbols behind him and all around him. Does not look like no frikkin alien in a spaceship to me!
3. Those gold artifacts from Colombia the AA *beep* say depict jet airplanes are just stylized depictions of fish and insects. Ancient Andean Indians often made stylized depictions of animals they encountered in their artwork.
4. The temple relief in Egypt's Dendera Temple that the AA wackos claim depicts electric light bulbs actually depicts an Egyptian god emerging as a snake out of a sacred lotus flower with his aura around him.
5. All of those prehistoric rock paintings that the AA *beep* say depict aliens in spacesuits actually depict either gods or shamen in masks.
Don't believe me? Just watch Ancient Aliens Debunked. You can find it on Youtube.
