The constellation of Hercules can be drawn two ways, upside down, or right side up. If you draw him upside down then one of his feet is near the head of Draco the Dragon. I can imagine the ancient believers in the Adam-serpent story seeing Adam crushing the head of the serpent.

I speculate that ancient religious mysteries (similar to modern LDS temple ceremonies) were remembered among some groups from star patterns. If you do these secret ceremonies in dark locations with a reasonably clear view of the horizon, such as in the mountains, the star patterns could serve as a memory aid to the religious mysteries. Furthermore, every time you look at the stars you could be reminded of your covenants with God.

In fact, the Adam-serpent legend might have been invented because superstitious people thought that the constellation arrangement was too much to be a mere coincidence.

I'm surprised the LDS church and other mystery religions don't use the star patterns to teach their secret ceremonies. They could invent new constellations peculiar to what they wanted to teach. It's another reason I think mystery religions are no more inspired by God than any other religious group.

I thought Shedir, the brightest star in Cassiopeia, meant the breast. If it is her breast she can be seen as a buxom woman in profile with her knees bent. I would be surprised if a sexy-looking constellation was NOT seen as such by lonely male travelers of the ancient world. Who knows, maybe Cassiopeia was the first example of pornography known to our ancient ancestors.

I disagree that anything in the stars or what modern research indicates ancient people thought about the stars gives good evidence for the existence of God.
