    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.

    During the day we see sky full of light because of sun's scattered light on our atmosphere

    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.
