headache

For one of those unexplained reasons, I found myself reading the first chapter of Genesis. It was different from all the other times I've read it. I was almost able to picture it.
1 In the beginning God created the heavens and the earth.
What did this part entail? Time, sub-atomic particles, fluid dynamics, gravity, electromagnetic spectrum...?
2 Now the earth was formless and empty, darkness covered the surface of the watery depths, and the Spirit of God was hovering over the surface of the waters.
I realize it was dark, but what did the earth look like? Was it a blob of water, floating there in space? Was there a misty cloud floating above that? I know this sounds silly, but I was really trying to picture it.
3 Then God said, “Let there be light,” and there was light.
Boom. Just like that. Can you imagine? Just by speaking it into existence(John 1:1-3). I find it very intriguing that light was created and there was no sun yet. Where did the light come from?
4 God saw that the light was good, and God separated the light from the darkness.
I didn't know light had to be separated from darkness. I just assumed it had always been separate. Another mystery.
5 God called the light “day,” and He called the darkness “night.” Evening came, and then morning: the first day.
All in one day? That makes my day seem a bit un-spectacular. I know this seems pointless, but I keep getting this feeling that there is so much more to God than I can begin to fathom. I mean, that's just five verses. My brain is about to explode trying to process just that. So little time...

bonus: The day and the night are the Lord's; let us use both to his honour, by working for him every day, and resting in him every night—Matthew Henry Concise
