I don't understand why I, or any other creature, can be possible.
When I think about it, the entire universe is all atoms which have no set path or direction and its just energy interacting with other energy to do something. We were part of that, cells were made from atoms as a mistake of them interacting, cells only do stuff because of atoms interacting. It makes me think we were all just an accident or that maybe this was set out, as in we can't control how we think and choosing to do it was just meant to be done.
Then there's OP's matter, I'm going to die so what's the point in getting a job or future? How largely will I contribute to humanity and what if I don't get to do it? I'm at school for 1/4 of my life, and it just seems like as I get older time passes more quickly. If I relived my school life 4 times I'd be dead, and it doesn't feel that long.
