I watched this documentary, but I am very skeptical of the evidence that they are using and their claims.
Ancient Aliens Season 1 Episode 2
The documentary uses ancient relics and evidences to try to prove that ancient civilizations built flying vehicles and tries to explain that by appealing to ancient people being visited by aliens. Any other information on the topic is much appreciated.
Can anyone with information on the subject tell me more about how much evidence we have for their claims?
