Ever notice there are a lot of ancient gods with wings?

Kukulkan, the winged serpent god of the Mayans.

Isis, mother goddess of ancient Egypt.

Eros, Greek god of love.

The Sumerians had Assur.

Karmadeva, the Hindu god of love. Although he is not represented with wings here, he is described often as a young man with wings.
And of course there are the Angels. There are several possible explanations for the winged gods, different cultures did influence each other, but that can't explain all of it.
Maybe it was a reflection of man's desire to take to the sky. I can imagine the ancients longing to soar the heavens like the birds.
Maybe all the winged gods were actually ancient astronauts, and the wings were part of some kind of techno suit. I say this because many of them are (such as Isis) are depicted with and without wings.
Maybe they were actual gods. I don't have any definitive answer. I don't think anyone does. But it is a pretty interesting ancient sync.
