While I don't go around preaching the "ancient astronaut/ancient alien theory" as fact, I think it is a pretty interesting idea. No, I do not watch the show "Ancient Aliens"
So when I found this picture I liked it. If you watched the last Star Trek movie, you saw that the Enterprise is in a fairly new planet where the men-like creatures that live there are in the early stages of forming an organized society. By mistake, the Enterprise's cloaking is deactivated at the wrong time and the ship becomes visible to the natives, who begin to draw what they see in the sand and they start worshipping it.
The crew of the ship would have come to be the angels in that case, therefore I decided to pick the name "StarTrek Angel"
