If god is omnipotent can he make a round square?
We can know something only after it has happened. Future events have not happened, so being omniscent and knowing future events seems to imply that something both has and has not happened, which is impossible.
To be omnipresent you would have to be a force, like gravity, but gravity doesnt have a brain, nor can it think, nor can any other force that is nonliving think, like god can.
