This is about a book called The Hidden Records by Wayne Herschel. If it's true that "all 50 pyramids in Egypt replicate the prime stars on 1 side of the Milky Way," then I think this is going to add to the deception and lie that mankind was created by someone other than God.  People who read this book might mistakenly think that the people on earth are descendants of an ancient race who came from outer space and built the pyramids in specific places to replicate star alignments in outer space.

There are other interesting links as well that you may want to read at the website.  I can just imagine some fallen angels disguised as aliens landing in a UFO on earth one day to deceive the people on planet earth into believing that they come from another planet and that they are either our creators or our relatives. Of course, fallen angels don't need a UFO to get around in, but it would deceive people in to believing that they were aliens from another planet that need UFOs for interplanetary travel.
