God put those insurmountable obstacles and limitations in place to keep man right where he is so he wont spread his destructive ways, as a result of his carnal, sinful nature, into the Universe to cause more confusion, harm, death, and destruction.
I’m convinced he will remove those limitations at some point, once he has put sin and evil to rest. But as of right now man is confined to earth for good reason. He’s like a Frankenstein monster compared to God who needs to be reprogrammed before he can be allowed to roam freely. This also shows the matchless limitless intelligence of God. Man is nothing compared to God. Absolutely nothing.
