Imagine a time in the universe before any consciousness exists, to imagine it you have to picture it and have some kind of reference frame for it. You look upon it. Now, take that away, because consciousness doesn't exist. What is now the difference between the universe existing and simply nothing existing? Resist the urge to try to imagine the universe existing, cause that reference doesn't exist at that time. My proposal is that of the strong anthropic principle. I think that consciousness is indeed needed for the universe to exist. Perhaps consciousness has always existed and may be the fundamental part of existence itself. Not necessarily human consciousness as we perceive it, but a kind of consciousness.
