The other poster responded to what happens, but here is the how do we know part. We understand very well how physics works, up to some small gaps that are irrelevant here. We know that information about the contents of your mind can't be transmitted outside your body in a way that would not be picked up by some of our sensors. People have tried to actually measure if there is any emanation from the body as a person dies, and there simply isn't any, in any spectra. So, there is no possibility of a soul living the body. Plus, any concept of an afterlife has no place where it could happen. There is no place on earth, in the clouds or underground, for an afterlife to take place in.

So, unless you think all of science is dramatically mistaken, we know with very good certainty that an afterlife is not a real possibility.
