If Prometheus stole fire to give to humans. Why was he in trouble? Because could not Zeus lightning strikes on earth create fire? Kind of seems like punishing a person for doing what you do.

The Greek pantheon wasn't known for being just or consistent. And technically, Prometheus didn't even steal anything. The gods could still make fire as they pleased.

Prometheus pirated fire. And the punishments for piracy are worse than theft.

There's a couple of ways to approach this idea. Literal and figurative.

Within the myth itself, the oldest version has the theft occurring after Zeus banned humanity from having access to fire because of fuckery with sacrifices (that was instigated by Prometheus). So, if taken is the myth is taken literally, it isn't about whether or not humans could pick up fire that Zeus created via lightning, or other methods, it was about them not being allowed to. By Prometheus giving them fire, he gave them the means to make it themselves rather than it being something the gods owned exclusively.

While that still has the hole that it was basically trying to play games to bypass the command of Zeus rather than giving something humans could have tried to steal on their own, and ignores that fire is a phenomenon of physics and chemistry rather than only being granted by a divine force; it's still the gist of that original myth as it existed when Hesiod set it down in writing.

Now, I think we all know that the myths weren't literal at all. There was no Zeus, and lightning wasn't the only source of fire for humans at all. There's not much in the way of hard evidence of how humans first harnessed fire, whether it was from external sources like lightning, or lava; or if it was discovered as part of the flint knapping process (little sparks can fly under the right circumstances), or other options.

And it isn't like the Greeks necessarily held every myth to be literal truth. They did have a degree of awareness of myth as symbolism.

And that's where the figurative comes in.

If your interpret the myth as fire being symbolic of technology, of thought and philosophy, of shifting from hunter-gatherer culture to a more stable location that allows for development of technology faster, then what Prometheus stole wasn't fire, it was the essence of divinity, the spark that made the gods other than human.

In that respect, you have to understand that Prometheus wasn't just some rebellious underling. He was a Titan, descended from the oldest gods, just as Zeus was. He was a god of fire, and in some myths was the one that made humans, shaping us from clay. Which is obviously not unique to Greek mythology, but it sets up Prometheus as not only our creator, but our champion among the gods and titans.

Indeed, he's credited in myth with bringing us more than fire. Art and science were credited to him as well.

Taken as a story about our place in the world, and how we exist as thinking beings, Prometheus is our drive to understand the world around us, and fire is our harnessing even the most primal of forces to our wit and will. It becomes a story of humanity being more than reactive, animalistic creatures; of us seeking to understand the world around us in a way that no other animal has been seen to attempt.

That fire is the fire of creation, of science, of poetry and dance and song.

And, it's also possible to interpret the myth in other ways, but there's a limit to how much is readable on a screen before the eyes and brain nope out, so I'll leave it at that.

I will add that most libraries will have a copy of Bulfinch's mythology. It isn't necessarily a perfect source on Greek myths, but it does a good job at being as complete as possible at the time it was written, and doing so in accessible terms. With it being the default text for a very long time, it's also ubiquitous. Even if your library doesn't have a copy, there's project Gutenberg, and you can find torrents or other file sharing sources for it, for free. Amazon usually has free versions of it available too, though I haven't looked in a while.

Oh, but when I say that Lucifer was a hero for getting humans to eat from the Tree of Knowledge I get called a Satanist!

The fire that Prometheus stole is a metaphor.

Zeus feared that with fire, humans would become powerful enough, maybe not to rival the gods, but certainly enough to stop fearing them so much, and to stop relying on them.

Zeus believed (rightly so) that humans who could master fire would undermine his power and control over them. This would be a threat to the stability of his rule over the pantheon.

He wasn't a loving god, and he never really approved of us to begin with. We were just playthings for the gods, created from the earth, but animated by esssences from the gods (tears, sweat, blood, I dont fully remember) and made in their likeness, with big intellects and free will, but smaller, like dolls.

Then the gods started breeding with the humans and everything went completely to shit.

The Olympians are a bunch of whiny ass petty excuses for gods.

For the Greek gods, the greatest sin was attempting to be like them.

Clearly Zeus was mad that Prometheus was... stealing his thunder.
