Notice it says "waters" not "water". The latest theory is that all those subatomic particles, before being transformed into nuclei... exhibited the physical properties of liquids... therefore they could be the waters that Gen. refers to. First came the subatomic particles in the form of waters, next came light... Just as described!
yes, I read some work on that, that it was water that was the basic building block of life, that God used water to make the ground, to eventually make Man
Water is used in many analogies, the most prominant being LIVING WATER, I guess
