The evolution of the Homo sapiens and the great enigmas of the history of humanity , find explanation in the existence of alien divinity in meat and bones. The civilization would be therefore a gift of these alien divinities. This is my opinion. You thing thought of it ?

Civilization is a natural consequence of human evolution.
It is possible that aliens had contributed in past, but only when humans were ready and in a limited way. Also, every time they intervened, consequences were not too good for humans.
This is just my opinion.

journey.......I agree it is possible that ET travellers may have helped evolution along......its just not likely we'll ever find out exactly when and where.....

You are right, it is hard to know exactly when or where or even how, however, we might find some examples in old testament.

journey......maybe we can get some from the bible.....but I think it occurred at the very beginning and was perhaps helped along to create and guide life 3 or 4 billion years ago.....but then as I said who knows.....
