.....interesting , I would go back to Egypt just before the pyramids were built, Stonehenge ditto ,call in on the Aztec’s and the Incas, all which would help to either confirm or trash Erich Von Danikan’s theories!
Erich Von Danken! That's a name I haven't heard in years. I read his book approx 30 years ago and I am quite interested in astronomy, so every time I'm out in the garden fiddling with my 8" instrument and I see Epsilon Bootes in the night sky, I think about his theories re: aliens!
