Yes, key words indeed. But if we look at the long line of could bees in our history, I'd say it's gonna get accepted (as most probable explanation) in the scientific community sooner or later. Just think of these: The lighting could be electricity, not Odin, We could have evolved instead of being created. The Earth could be billions of years old instead of 4000, the vase could have been broken by the cat, not the ghosts.
