Simple. we keep advancing our technology until we can build a machine or genetically engineer a person who can see into the other dimension and learn to fully understand it, conquer it etc.
God created technology.
Does that then put our machine inteligence/genetically enhanced Human on a par with God? Maybe.
I heard it said once, that God could exist in like the 29th demension. If that's true, we got a long way to go.
What if we don't stop there but keep going until we surpass God?
I highly doubt that will happen.
1st off, Jesus will probably come back before then, and allow us into the next demension. or
2nd God has designed the universe to not allow it no matter what.
It's just common sense that "if" God exists, and he created all this, we would not be able to "surpass" it.
