Now honestly if you think about this hard enough, something about the fact that you came to be at all will strike you as bizarre. You know not what occurred before you became, nor do you know how this occurred, why, or ultimately where you are going. However, you can now definitively say that you are, you have become the singularity, your individual telos has found residence in the flesh of an animal. Here you sit, reading this, converting light and color, shape and sound, sending a will to magically type your response. Fingertips and hands, to you alone they are enslaved. Your attention if divided can be trained into submission. You read this and wonder immediately what you can say to ameliorate the sudden existential discord, the fact that the curtain can be pulled on your certainty.
So how did you come to be? Was it karma, the negative and positive energies of your soul swirling in the firmament to reside in a host, was it a slighted god, molding you like craft-work. Was it a random conflux of hidden energies that happened with a probability never to be repeated, a quarky buildup of matter so random it would take a trillion dice? Who's to say you will not immediately occur again when a new pilot is required for some random new brain in the universe. Most likely that is what will happen. Once you land in an immortal coil as opposed to a mortal one, you might not have to keep reincarnating. Though I would argue at this stage that you are clearly constantly incarnating. You can say with certainty that you most likely had a long string of failures to find an immortal host, or if you ever could not age, you must have accidentally died.
The only way you could stop coming to be is if there was never again a seat to be filled. You clearly were not in the very beginning, or most likely were not, but no vacant seat is left open when they are built. If there were a trillion situations where consciousness could reside and over time that was subtracted to nine hundred ninety-nine billion nine hundred ninety-nine million nine hundred ninety-nine thousand nine hundred ninety-nine, perhaps one less soul that kept recycling could exist, or their incarnation would be put on hold. Of course no time would pass for the soul once it is waiting. And to finish, I myself am a atheist/agnostic, but I know this cannot be the first time I was, or is it likely it will be the last time I will be.
