I have.
Someone posted a video and it intrigued me so much that i ordered the book.
I am very similar in thought to him. That somehow our species has amnesia and our history is MUCH more than what we think. There are good reasons to believe that much of our mythology is based off of ancient civilizations that have almost been completely erased from our earth. I mean cities that were largely populated with all sorts of life from other planets that left here thousands of years ago and either have not returned or are unable to return for some reason.
This is interesting too, but you do realize that the Sumerians are in the Bible right? They are referred to in Genesis...they are the people who lived in Mesopotamia but i think they are called people of Shinar or Sinar or something like that. You could probably find it somewhere.aside from the civilizations mentioned, another one that has an interesting account of aliens being responsible for life on earth is the Sumerians. their creation account and flood story, for example, are said to be hundreds of years older than the Bible accounts but yet they are pretty similar. they believe that aliens from outer space came and grafted their DNA onto neanderthals or something like that, if I recall correctly.
But I guess I find it hard to believe how many believers don't like the idea of an extra terrestrial presence. I mean, if you look in revelation of in the OT prophetic books you see all sorts of strange life.
