Actually, if you look in detail at the initial stages of the big bang, they are very reminiscent of the first few verses of Genesis as long as you allow for "waters" not to be literally water.
Consider that in the early stages of the universe it was very small. Yet it still contained all the matter and energy in the universe today. But the matter could not exist as matter. In the high level temperatures and densities that existed in the first 3 minutes of time, it was impossible for atoms to form, and without atoms you don't have the structure of a material universe.
The structure of the universe at the time was that of a sort of "fog" of energy. It was dark because even though photons were abundant, they were in constant interaction with other particles, constantly being made and unmade with no opportunity to shine.
Every particle that eventually formed the earth was present in that energy field, but it couldn't form the earth yet, because the universe had to expand and cool down enough to make atoms. Not until then could light shine, and it was even later that the first galaxies and stars could form.

Now I am not saying the biblical writer thought of water as being anything else but water. He may have been inspired but he was not clairvoyant. Genesis does not refer literally to the big bang or any other modern scientific theory.
But the parallels are intriguing. In Genesis we have an endless mass of water in which the earth is without form and all is dark.
In big bang theory we have an immensely small, immensely dense cloud of super-hot energy in which matter cannot form and light cannot shine.
If I were looking for a scientific description of what Gen 1:1-2 is describing, the big bang is a very probable candidate.
