Care to prove me wrong?

If you had a good understanding of the universe, you might understand.

Why political leaders would deify themselves as Gods, but rather lived their lives according to elaborate myths that were based on constellations and astronomy.

I'll prove you wrong after you attempt to prove yourself right. Planets are roundish rocky or gaseous masses above a certain size threshold which orbit around a star in a certain type of orbit. Those in our solar system appear to us on Earth as stars which take un-star-like orbital paths.

I could see a variation and extension of the Gaia Hypotheses leading to the opinion that planets are gods. But I don't see, on the face of it, how the opposite works.

Care to prove you right?

do we still live in ancient times where we sacrifice animals and/or people to have better crops for the season?

whose gods? from when?, yes planets do get represented as gods in mythology. Planets are alive in a way, though some may not appear to be in our dimension. Some see planets as the next layer up in bodies of consciousness, gods only to their inhabitants much like the sun is to the solar system and the super massive black hole is to the surrounding galaxy eminated from it. The heirachial tiers or fractals of god so to speak.

Would you worship that which was created?

Or the God that created them?

You're a pagan.

Prove me wrong.

For the most part, probably. That is also the Occult interpretation, is that age old knowledge of celestial bodies was passed down, eventually becoming personified and dilluted, etc.

But God(singular) could be the One, or Gravity vs. Electromagnetism.

Really it is more complicated I think. There are different contexts and different purposes for the word God.

Knowledge of the night sky and the procession of the equinox over time (2600-year cycle) was very valuable, secret esoteric knowledge in ancient cultures (Egypt/China/Mayan Empire, etc.). Because they had a monopoly on this kind of knowledge, the priests could predict events like comets and eclipses, and use them to terrify and awe the dumb masses. The priests could predict an exlipse and then use ritual to "make it go away," which was a demonstration of their power and thus a tool to help them preserve the respect of the masses and the warrior classes.

Lots of myths encode this kind of celestial knowledge using secret imagery. It was a way for the priests to preserve and pass down their knowledge while keeping it secret. "Hidden in plain sight." The lurid and colorful imagery of mythology also was a memory technique that made the constellations, the equinox procession, and other features of the night sky easier to memorize. For example, "the twelve labors of Hercules" were references to the twelve constellations in the Zodiac. The bible (especially the new testament) is laced with dozens of references to astrology and astronomy. In fact, the Book of Revelations (while also serving other purposes) encodes a great deal of information about the way the constellations move over vast swathes of time. For example, "the woman clothed with the sun" = sun rising in the constellation of Virgo, while "riding on the beast" (located over the constellation Drago), etc. etc. Astrotheologists can and have unravelled the secrets.

I wouldn't go so far as to say this is the ONLY purpose of myths and sacred texts, but it plays a big role. These kinds of images are hidden like a code throughout myths of many different cultures.
