[DC] Where did the meteor that gave Vandal Savage his immortality come from?
gpt
Outer space.

Seriously, nobody knows anything about that meteor.  Savage himself was just a caveman then.  And while he gained super-intelligence and immortality, he didn't instantly gain *knowledge*.  It would have taken him a while to figure out how the world works.  It's still just a weird rock to him until much, much later.  It's not like he instantly knew he was immortal and that the rock had caused it.

By the time Vandal Savage figured out what had caused his changes, the meteor itself was long lost to history.
