I have nothing against aliens, but I don't think they are necessary to explain any of the the mysteries of the past that I am presently aware of.

I'm sure the universe if full of life. I just don't see any evidence that "ancient astronauts" visited planet Earth.

So I regard this as an area for other people to explore if they want to, but its not for me.

Yes I'm quite familiar with Erich's work. I don't "dismiss" it out of hand but I think there's a better explanation -- a lost human civilisation -- for most of the anomalies he pointed out.

Have to stop on this now, but thanks for your comments.

Allbest, G
