Oddly enough, our own abilities to create sentient beings will someday act as the "proof" that there really is a God that all the atheists have screamed just cannot be so. However, this will act as proof of *a* god, but not necessarily the format of God that most religions want you to believe in.
God is a verb, not a noun. Creation is omniscient, omnipotent, and omnipresent.
