~300 to ~400 million years ago - wasn't the placement of all the stars in the night sky entirely different from the POV of earth?

I made an edit.
I think (but don't know, I'm not an astronomer) the ancient Greeks and Egyptians saw a different sky than we do because of the orbit around the center of the galaxy. I'd have to look it up, but that might have changed how constellations looked.
I do know in the far future (like several billion years), stars will be farther apart in the sky and eventually as the universe expands, you won't see anything except pitch black. It's spooky stuff ._.
I once went to a Wikipedia page with a title like "the far timeline of the universe" or something. Putting it poetically - I think it was that the stars go out on earth in ~100b years.

The far future is truly Lovecraftian and hard to fathom. Eventually star formation will cease, most of the timespan of the universe will be the "dark era" where black holes slowly evaporate due to Hawking Radiation. Then there will only be light, and when there is only light then time itself ceases to exist as a meaningful construct. Space, too, perhaps. Then there is an alternative, even longer ending, if it's possible for light itself to decay.
Rage, rage against the ~~dying~~ decaying of the light.
