What you and I can do and what God can do are two entirely different things, right?
Well ... God made all things, seen and unseen ... but that isn’t really the issue with me. The fountains of the deep, as stated in the Bible, were certainly one of those things he created, but I don’t see the Ringwoodite as being those fountains of the deep.
I don’t think those fountains of the deep are there any longer, but have been used up and the remaining amount of water given up back then is now in the oceans that we see with us today.
Again, it has nothing to do with what God “can do” but with what he “did do” ... :-) ...
