I agree with the fact that the majority of valid UFO-sightings are demonic, but, in the case of the Apllo 11 mission sighting, I reason that it was an angel looking out for those going to the moon. Back then, NASA used to be moral in their quest to understand God's creation, so naturally, when trouble arose, there was an angel there to help them in such a way that they made it back to earth safely.
Now I mention the space-junk sighting in my book early in the chapter, and I never could tape it and never saw it again after the first and only time I saw it back in 2000 A.D. I don't know if it was a demon or holy angel, but whatever it was took off at the speed of time! (or, the speed of live...like FoxNews, hehehe!!!!).
Some of the angelic life my be indeed flesh-like creatures from other dimentions of space-time. M-Theory, a metaphysical conjecture, has some seeds of truth has to the notion that there are more than 4-dimentions of space-time. 11/12-dimentions in a multiverse would explain the Biblical data perfectly without materializing God. I explain some of this in my paper, but, what isn't emplained will be in chapter two.

Evolution is polytheistic because (a) the Babylonians and Egyptians came up with the framework of modern evolution and (b) evolutionists who understand the authenticity of UFO-sightings try to materialize it all in an explanation of evolution --which would, in theory, reach a polytheistic conclusion. I've studied many theories from SETI researchers and they all seem to believe that alien life evolved on some planet in our solar system (or some other place close by). However, the Bible identifies who they are, providing excellent descriptions that become clear to the modern mind.
