That renders it a pointless question, though. This is acting entirely outside every law that governs reality. An answer of "rainbows & gumdrop kittens" is equally valid as "willed into being".
I will grant that obviously if you believe this already, it's not hard. But for someone who simply can't, it's both puzzling and infuriating(not your fault mind) that "God willed it" is anything remotely like a satisfactory answer. It doesn't explain anything.
Neither can it. Everything that goes on outside the boundaries of this universe is completely undetectable by us. Science is limited by the scope of the universe, everything beyond it can only be understood by reasonable thinking.
If the debate is set that there is a Creator who created this universe, then this Creator must be all-powerful, as He created the entire universe and everything within it, detailed every object, designed every creation, etc. If He is all-powerful and created the entire universe, we can also logically assume that He knows everything, because He designed everything to begin with. If He knows everything about what He has created, then He sees and hears everything (in His own unique way). If He sees and hears everything, we logically assume He is near everything, (not physically).
We instantly assume all these things because of the first fallen domino, that there is a Creator who created the entire universe. Then we logically go on from there. So if this Creator exists, He exists outside of space and time. Existing outside of these boundaries means that when He creates, it is not creation that follows a linear history, where A will turn to B, and B will turn to C, because that requires change which can be measured, which is time.
God/The Creator exists outside of time, so God can create, destroy, create, destroy, with virtually nothing. Things will pop in and out of existence according to His will.
Time will just be an illusion for whatever He creates within the creation.
