Is it true? Not the aliens. Maybe not true, but accurate even. The astonishing claims of these ancient alien investigators. The alignments of ancient monuments, the similarities of geographically distant sites and their placement on the globe. How much is empirical fact, how much is wishful thinking, cherry picking, distortion?
This is on my mind, but only because I settled on a weird TV channel.
The same sources say that Stonehenge, the big pyramids, the great wall of China... etc were all made by aliens.
