You are not making any astronomical sense Lover. Your photographs are wasted because the human eye doesn’t work like a camera. A camera has the ability to keep collecting light radiation and building brighter and brighter images until the film is overexposed. The eye doesn't overexposed things.
Observational Astronomy was almost certainly done by very smart and yet, also very imaginative people. I suggest that they worked together to categorize and make sense of what they saw in the night skies. In open country without any light pollution the stars are, indeed, much brighter. But observation can be done on an all night basis when early in the session the bright stars were easily seen unencumbered by thousand of tiny background stars. The effect is kind of a gestalt process, between foreground and background.
Traveling at night, and traveling by sea made knowledge of the stars important. As the good Doctor said we don’t know when the Zodiac was first developed but I think it obvious that it had to precede the Egyptians and the Mesopotamians.
