Meaning is always around us, it is something that can come from anywhere, when we ”find meaning” we are really just changing the way we see the world to be able to understand the already inherent meaning all around us

I would have to say that in the situation of an omnipotent being, he would have the knowledge of how to change the universe in any way, but only through science, I believe he could control the process of chemical reactions and forces even unknown to us now, but I don't believe that he could break the fundamental laws of the universe just because he knows all.
