Mystery multiplication

• There was a noise in my house and I can't explain it: therefore it was the ghost of a long-dead person.

• There was a light in the sky and I can't explain it: therefore it was an alien spaceship from another solar system.

• The universe started and I can't explain it: therefore an immortal, omnipotent, omniscient, intelligent being I choose to call "God" did it (and he dislikes gays and ham for some reason).

Something happened and I can't explain it: therefore the answer is something which is many orders of magnitude more unexplainable than the original mystery.

The correct answer may just be "I don't know"…
