ANCIENT ALIENS

Commonly referred to as Greys, Watchers, Entities, Chandlers, Visionary Time Travelers...who do these skulls belong to? What about the Crop Circles? Is there a connection to them and our own genetic engineering? Or is this a separate race of extraterrestrials altogether? Sasquatch/Forest People, Nephilium/Paracas/Stone Builders, Mound Builders, the Giants of Ancient America, and Queen Pubai's Anunnaki DNA are ones we can't test but have been said to be connected. So are we?
