Beleive it or not, that is what the young earth creationists say when it comes down to it. Its like the classic solipsist arguement: no can prove to me they aren't automatons controlled by an evil wizard, so there is no way I can really know if there is anyone else besides me. There is no way anyone can prove that God dint just "make it that way", to fool us, or test us. It's a completely unfalsifiable arguement.
