Yes, God could create a power that does that, but he doesn't need to -- since mankind has already taken care of that. It's called illusion, or error. We can easily create illusions, that although they may not actually exist within fundamental reality, can seem very real for us on the level of experience -- and can serve to limit our experience of reality if we form them into absolutes and then apply them to ourselves, each other, science, life, etc.
I think that we all are likely to do that about some things and at some times. I do not exclude myself from the propensity to be fooled by self-created illusions or false assumptions, nor do I see that scientists are necessarily exempt from it, either.
