I don’t believe that’s possible, depending on what you mean by “supreme creator.” If you’re talking about the being that created everything we can possibly perceive, witness, or even theorize, then I don’t think so, or at least I don’t think It could have always been composed of atoms.

If this being created atoms, it would be logically inconsistent to consider this being to have been consisting of what It created. That being said if, this being also created the laws of logic through which we are capable of understanding anything at all, then why not? If these laws of logic did not exist before the creator of these laws of logic, then why would this creator be bound by them?

TL;DR nobody can possibly answer this question with any grounded certainty whatsoever.
