He doesn’t only exist outside time and space. He had to have existed outside time space for him to have created time and space. But nothing prevents him from also interacting with or being inside time and space. 

Right, I am saying painters exist and they make paintings because everything was created. Are you saying paintings (or anything) don’t exist because nothing was created? Is your stance that everything always was since nothing was created?

Thinking nothing was created and stuff just always existed is an assumption perhaps just like thinking there is a creator can be seen as an assumption. One makes more sense than the other. There is no evidence that there can be an effect without a cause. But there is abundant evidence that effects have causes. 

 "In nature nothing is created..." Lavoisier. Theres no evidence that anything was created, ever. Cause and effect are terms to the transformation of what exists, theres no logic in associate cause and effect to the creation of something. 

 If there was no evidence of intelligent design (DNA, laws of physics, etc.) and it was just blobs of matter floating around that would be a persuasive argument. But just like when I see a message written on the sand that says “bob loves mary” I don’t think it was randomly created by the waves, but rather a message created by an intelligent being. 

But even if one is obtuse enough to dismiss all that, at best one can say we don’t know if there is a creator or if everything always existed. But one can’t claim like you did in the original response that there is no creator 

 Theres nothing in the universe like "bob loves mary", nothing.
I was responding you, not explaining how I can prove that god doesnt exist. I can, if you have courage. 

 Of course there is. Look around. We are part of the universe last I checked. But even if you selectively exclude humans from what can be considered evidence of intelligent design, we still have millions of life forms where even the simplest of them have much more complex messages in their DNA than “bob loves mary” 

 You already read about junk DNA? Or Endogenous retroviruses? 

 Assuming there is junk DNA ( https://magazine.washington.edu/feature/no-such-thing-as-junk-dna-researchers-say/ ) that doesn’t imply that the rest of DNA isn’t far more complex than a message about Mary. It’s literally language, a blueprint how to make beings.
