What is the universe inside? Clearly there must be something far larger, logically that holds us in or no?
Nothingness? come on, I've never heard of even a likeness to nothingness other than my own intelligence.
So To say based on logic there is nothing outside the universe is just hot air. I understand AV's point
about looking within the u. First of all to prove a negative about existence you must have positive
evidence that he doesn't exist. Now you must have simultaneous vision of the entire u. And even moreso
at the most fundamental level, he may be the size of an atom or less. He for all I care can be spread
throughout the thing diffusely. You aren't going to know unless you have hard data, that he doesn't exist
within the universe. Outside the universe is tricky, nobody knows what is or isn't there. Scientific american
says there may be many universes( spatially I don't understand that because if there is nothing, there is
no space either- or fill me in on that- or I'll just go read wikipedia like you will) God certainly did exist in the
universe at one time and you could have found him in israel 2000 years ago. The bible says he isn't here
yet so you won't find him but wait. I am not certain but judging by the way the world is heading towards
pure idolatry of money and mind and power we're almost at the point where he will be experimentally
detectable again. Or so I think...

And by the way, God is within and without our universe as we speak,
he is the holy spirit. He is by no means detectable scientifically however and that is a big bugaboo.
