Then how did it all get created if there wasn't a creator or creators?
Correct.
Within the matrix of the visible (and invisible) stuff that was created also lies the "science" that was created along with it.
Could be he's creative by nature. Humans are. And humans were created in his image, correct?
For someone to hang with and to talk about "things" and such. (See the story of Adam & Eve.)
On earth as it is in the heavens, things work because of a slew of conditions that came before them, mostly. For example, oil and gas is in the ground and it took millions of years to get there. Many minerals, like gold, etc..., are extracted from fissures and layers of rock that are all twisted and warped. That also took quite a while. (And I don't believe I have to explain the "science" behind those two examples.)
There very well could have been a good reason for it to have been created that way. Reasons we don't yet understand. But that's the way it is and also gives man an opportunity to use those "things that work" for us in which we were given the ability to figure out.
Making those "things that work" obviously took time to make. Six days, according to the Bible. But that doesn't necessarily mean that a day to us is the same as a day to the creator(s).
So, my question to you is: "Why wouldn't this great creation be created without a history behind it?"
