I have the first 'Chariots of the Gods' that I bought in about 1968 when I was in college. It is falling apart because I thought the premise was odd, so I kept researching the idea that extraterrestrials were involved with our civilization. To use amedical term, I have never found anything to rule out the ideas that Ancient Aliens expresses. I never miss a show although I have seen all of them several times. I'm glad some new shows will be coming soon.
I found an article about Avangard, the hypersonic rocket cdomplex glide vehicle that was demonstrated to the US inspection group in accordance with the New START treaty procedures on November 24-26, 2019, the glider flew at 27 times the speed of sound. As I figure it, that is more than 20,000 MPH. Hmmm..Alien technology????
