The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters.
There are so many different directions that one could go with a verse like this. I believe that most people would tarry on the phrase "without form and void" to try to understand what was going on there. There are some who look to this phrase to support that the earth (and the universe?) were around before this particular creation. I won't go into detail, but I bet you could do some Google searches to find a wealth of information.
To debate those words would be interesting... But lets take them at face value. God just created time and space, now He is entering into both to hover over the waters.
Instead of being moved to debate the words of this passage... be awed by it. Be amazed that God, THE God, has entered into time and space and He has a purpose. It doesn't say what He was doing while He was hovering over the waters, but He was.
Be thankful today for this God and His creative works.
