When I was a kid, I didn't know where I began or where I ended. I still am not convinced by my own physical existence, that everything I am and am not is defined by what is separated into inside and outside by a thin skin. I am no more than a bunch of elements that were scattered across the universe by some supernova. They just so happen to come together right now in this body of mine. But, after I die, I will be reduced to elements and scattered across in the universe again. It may be natural to distrust the entity. I am just part of the universe, and I will return to the universe someday.
