During the day the number of galaxies doesn't change and we see the sky full of light.

I know, I am just pointing out that may be it is not only the number of galaxies that matters.

The number of galaxies viewable from Earth is finite, and even the brightest galaxy [beyond the milky way] is difficult to see with the naked eye.
