To put it another way, just because humans can do things ants can't, and relative to ants seems godly, doesn't mean we can literally "do anything." We're still bound to the same physical reality and physics the ants are. While much of what we can do seems like acts of gods relative to what ants can do, to us it's perfectly mundane and unremarkable. To the ants it's absolutely godlike.
Similarly, if a god actually exists relative to human beings, it too might be ablew to do impressive things, but will still be finite, limited, and bound to scientific laws and limittations.
Just because ants can't, and humans can't, doesn't mean God can't. He can and He did.
