There are only three (and I will challenge you to come up with a fourth) potential origins for the universe.
Either it:
A. Created itself out of nothing
B. Always existed
C. Was brought into existence by something outside of this universe, a "supernatural creator"
It cannot be A, for a rock cannot create itself out of nothing, nor can it be B, for a fire cannot burn forever. You may recognize those reasons as alternate ways to state the first two laws of thermodynamics, which are neither matter nor energy can be created or destroyed, only changed from one to the other, and entropy in a closed system always increases.
Theory A violates the first law, because it states that the universe came into existence on it's own (energy/matter created), and Theory B violates the second law, because it states that the universe has been "burning" forever, but it's not cold and dead, as it should be due to the second law stating that entropy always increases (fire burning forever).
The only remaining possibility is that the universe was created by a "supernatural creator", something outside this universe.
If you think that it's not one of these three, please provide an alternate theory that does not incorporate these.
