Naturalism 101

"Wishes and hopes are one thing, the ways things are is another. So if you want to know how things actually work and what actually exists, as opposed to getting stuck in what might be wishful thinking or delusion, you should be scientific and empirical. You should seek good, objective evidence about what exists and how things work."

Naturalism is simply the default scientific position.  Since the dawn of modern science about 400 years ago, there has been no empirical evidence for anything supernatural, in spite of many testable claims to the contrary.  Thus, the reasonable conclusion is that there very probably is no supernatural realm.  As Sean Carrol says, "Naturalism has won."  Yes, there MAY be a supernatural, however, without it revealing itself to us, it is, at best, a soundly falsified speculation not worthy of our consideration.

There are not two different worlds, the supernatural and natural.
