Ancient Astronaut Theorist, and In Search of Aliens host Giorgio A. Tsoukalos adds his thoughts on what the Ancient Astronaut theorists believe about the global practice of mummification. Is it proof that highly advanced extraterrestrials visited Earth in the distant past? Could our ancestors have witnessed a form of biological hibernation and then mimicked it with mummification? Could mummification have been an attempt to recreate suspended animation so often connected to extraterrestrial space travel? Or could the intention have been to preserve the body for future DNA removal?
