In average, as the earlier we go back to the past, the brighter the night sky would have been since everything is accelerating away from each other in the universe.

Or any super novae event close to earth would have brightened the sky significantly since they were observed from cave men to early astronomers in China.

I wonder if the time period between the formation of the moon to the settlement of the moon into its current stable had bright night sky dominated by much closer moon.

Apart from short-living supernovae and similar events, everything you can see with the naked eye is gravitationally bound to us (and all bright objects are in the Milky Way). The expansion of the universe doesn't matter for naked-eye views. The number and brightness distribution of stars depends on the time but I don't have numbers for that.
