Is it true that there are 13 mystical sites near the Greak Island of Delos which, connected by straight lines, produces a perfect Crusader knights Maltese cross, a perfect gigantic pattern that could only have been created from a vantage point in space?

You all are going to think I've fallen off the deep end, but I'm currently reading a book that I thought was about Freemasonry, but is actually about aliens having begun human civilization. Now, I half think this is hilarious, but I can't help wondering about some of the more unbelievable "facts" presented at the end of the book. So I'm going to post several questions based on "facts" presented in the book. Please feel free to give evidence or alternate explanations against these facts, because I really don't want to become a nut who thinks aliens kept humans as slaves, genetically modified us, and mined our planet millions of years ago.
