Is the Universe infinite? Is space infinite?

Many scientists had originally thought that the universe might be infinite and eternal. However, there was a major problem with the theory. If the universe were infinite, the amount of light falling on the earth would also be infinite (assuming an approximately uniform density of galaxies throughout the universe. The reason for this is that the volume of the universe increases 8-fold with doubling of distance, while the decrease of light is only 4-fold with the doubling of the distance. The result is that the amount of light falling in the earth would double every time the size of the universe is doubled. Therefore, if the universe were infinite, we would not expect the sky to be dark at night. Since the night sky is dark, we know that the universe could not be infinite (Rich Deem - http://www.godandscience.org/slideshow/sld001.html.)

So if the universe is finite and there is evidence of darkness beyond the farthest known galaxy (approximately 13.7 billion light years away - edge of the universe) then at least for now, we can hypothesize that space continues and appears to be infinite.

This indicates a point of origin (science calls it singularity, more on this later) where the Creator decided to create time and matter and set the universe in motion into empty space.  In other words, this is the dimension we humans live in.  (I would like to add that I believe that the Eternal God at this point became also the Everlasting Father, more on this later.)  If the universe was infinite and the observation of the amount of light falling on the earth is correct, it would not be possible for us to distinguish the celestial lights and bodies and therefore would have no reference point of time and space. 
Coincidentally, God states a purpose for this phenomenon in Genesis 1:14 - God said "Let there be lights in the expanse of the sky to separate the day from the night and let them serve as signs to mark seasons, and days and years....
