This is fairly stupid pop philosophy. It's really a question about the nature of reality mixed with the fantasy that it's possible to to somehow step outside of reality, or that there is an entity creating and controlling reality, that becomes a fantasy about god existing. Our reality exists entirely in our own minds, in that sense we live in a simulation we create in our brains. Using science to determine the details of our environment is useful, but speculating that there is something beyond what we can possibly study (by definition) is pointless.
