I imagine things wont be much different except Greeks and Romans and Egyptians (and all other ancient civilizations) might have invented one more “God” for the black hole.

As a matter of fact, many ancient civilizations have “Gods” for the point where moon’s orbit intersects with Earth. https://en.wikipedia.org/wiki/Lunar_node

In Hindu mythology - we have two “shadow planets” and gods called Rahu and Ketu https://en.wikipedia.org/wiki/Rahu these points are no real planets or moons - but are given the same status.
