Since most scientists favor the “evolution” thing, that fits nicely into the scheme of things.
“And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.” Genesis 1:2
That's the problem with Genesis. It's way short on details. I'll bet God used icy comets and other debris to fill the oceans. Same with light. Genesis should have been more specific about using a nuclear reaction to get the sun going to light the earth. And the whole 7 days thing? How long is one of God's days? I mean, for our God who has been, is and always will be in eternity, does he/she really keep a calendar based on how often our tiny world spins on its axis? You think he celebrates his own birth day?
Just some thoughts to ponder. We are such simple creations of our God. But the complexities of God's simple tasks are beyond our comprehension.
