In a few words; you're crazy to believe either. Not crazy; just delusional.

The lower images are the sensationalist interpretation of the 1980's "Ancient Aliens" theory - The history channel did video presentations of the views of author Erich von Däniken in his pseudo-scientific Chariots of the Gods" book from the 1980's. He became rich and famous from his book...and the video had mixed reviews....

The conclusions that were made... that the ancients did such incredible things, that they must have had "alien assistance" has since been countered (more recently) by more scientific works that prove that ordinary people were, indeed capable of making incredible things....from the huge Nazca Lines Geoglyphs to the Egyptian pyramids, to the "gods" (image above) allegedly piloting rocket ships....were all proven to be just the real images of really good, really hard working, really talented ancient folk...seeking meaning to their existence.

Science has recently explained most of these "phenomena"and is now doing what Religion tried to do for thousands of years. Explaining everything from the creation of the universe to the evolution of DNA....

Hence I, for one, say that I do not (a) know (gnostic) that gods exist -nor that aliens exist.

I have not seen one shred of solid evidence....and I read Chariots of the Gods"- as well as the bible. So I remain, Agnostic.

No different

It never ceases to amaze me of the level of detail that these religions went into to convince and control their flock.

Bird head gods are so last eon.
