i suppose that's a fair assessment to make, but for me personally that isn't how I define a God, as there are several deities within older mythologies and religions that weren't exactly omnipotent (and even mortal ones such as the ones in Norse mythology). to me, the only real quality that endows one with the aspect of Godhead is the abstract concept we refer to as "divinity", or rather some intrinsic separation of the creator from the created, as it were. now, certainly, if some higher order lab tech created the simulation, you could argue that they are indeed separate from it, and in having the power to create it, they do have the power to modify any aspect of it, but I still don't believe that imbues them with any sort of divinity. as far as I can see it, they could likely just be the same as us: a simulated being under the purview of an even higher order of complexity.

but ultimately the point for me is that I just don't believe in "gods". it's not that I don't believe that the archetypes and characters introduced by mythology could never possibly exist, it's more that I don't personally believe that there is any intrinsic difference between us and them other than just the order of complexity upon which our experience of life and reality is founded. i believe more that the idea of "God" is more akin to the sum total of all information within a given "system" (be that system a universe, multiverse/omniverse, or some even further abstract concept); not so much a demiurge or some active participant, but rather an emergent phenomena that manifests as a synthesis of all of lower orders of complexity beneath it. this does not imbue the Godhead concept with any sort of special or separate nature, in my opinion, and in fact if anything, implies that divinity in and of itself is more just a specific modality of consciousness detached from the ego and the perspective of I-ness
