Are we our bodies? Is a small person less than a big person, then? If we were our bodies, then when we lost an arm, or a leg, would we be less, would we begin to fade from existence? No. We are the same person.We are not our bodies; we are our thoughts. As they form, they define who we are, and create the reality of our existence.
Of all the major religions, or lack thereof, the atheist's is one of the best pretenders: his foundation for all existences, as well as moral behaviors for the permanent good of mankind, begins at science but ends at himself, the Napoleon complex of both intelligence and imagination. On the other hand the anti-theist wouldn't survive without a deity beyond himself to hunt. He doesn't pretend, he simply nullifies his own position.
