Reconsidering The Waters of Genesis
Well, even in english, not all waters are equal. From the brown muddy waters of the Mississippi, to crystal clear stream waters, to the dense salty waters of the Dead Sea, the differences in content abound. Yet they are all considered bodies of water and at least have H2O in common. But they are certainly different and perhaps the initial waters of Genesis were even more so. Maybe they didnt contain H2O at all. After all the ancients were certainly ignorant about the basic water molecule and perhaps identified waters based on their formless flowing characteristics. Perhaps waters, or mayim, is the best term to describe a mass that isnt solid. Perhaps the primordial earth was simply a liquid-like mixture of the basic elements of our world. Would mayim have been an appropriate word to describe this? Perhaps.
You are not too heretical there, or at least you are in some pretty good company
Calvin Commentary on Genesis 1:2
I will, in the first place, state what (in my judgment) Moses intended. We have already heard that before God had perfected the world it was an undigested mass; he now teaches that the power of the Spirit was necessary in order to sustain it. For this doubt might occur to the mind, how such a disorderly heap could stand; seeing that we now behold the world preserved by government, or order. (46) He therefore asserts that this mass, however confused it might be, was rendered stable, for the time, by the secret efficacy of the Spirit.
(46) Temperamento servari. Perhaps we should say, preserved by the laws of nature. Ed.
Calvin Commentary on 2Peter 3:5
The world no doubt had its origin from waters, for Moses calls the chaos from which the earth emerged, waters
Barnes Commentary on 2Peter 3:5
the creation of the earth was the result of the divine agency acting on the mass of elements which in Genesis is called waters, Gen_1:2, Gen_1:6-7, Gen_1:9. There was at first a vast fluid, an immense unformed collection of materials, called waters, and from that the earth arose.
I think from Barnes commentary on Genesis that he subscribe to the Gap Theory, so whether he is describing the initial creation here or the post Gap chaos I am not sure.
