In short: Prometheus was a god who secretly gave the gift of fire to man for the first time. But, because the other gods held fire for themselves, they punished Prometheus by chaining him to a mountain top where an eagle would come every day and, essentially, disembowel him. And, because he was a god, his wounds would regenerate every day so that this eventually very fat eagle would always have something to snack on.
But if I may run with the myth analogy for a bit more, I think the true gift that Prometheus gave to the masses wasn't just the spark to light the bonfires. It was the example he set.
Not only that the heavens could be challenged, but that they MUST be. By everyone. That the cost was far outweighed by the treasures.
And when you do that, a new world can be born.
Imagine if we all strove to achieve what he achieved. Imagine if THAT was the standard.
Think of the universe that could be born.
Thanks for the spark, Steve. You'll be missed.
