I am wondering if anyone else also feels like I do. I try to be optimistic but I always end up thinking what is the point ? One day all of us are gonna die. I don't get it when people say they have a purpose in life and they can't go untill it's fulfilled. If it is to help another human that human is also gonna die so what is really the purpose ? Sorry if the question is vague
I think people can make up their own small purposes
in life, like to succeed at whatever, raise a family etc, but that's different to the question whether there is a general purpose
to life.
Maybe it helps being religious, as you already have a pre-packaged purpose, which is doing God's will, obeying his commands to get eternal life in heaven etc for the monotheisms, or e.g. following the eightfold path to eventually liberate yourself from desire and the cycle of death and rebirth for Buddhism.
But if you reject the religions as man-made systems of social/psychological control, it is difficult to see a purpose to life generally, at least with our limited access to whatever reality is.
You could create your own system of values and purposes like Nietzsche said, but this would still be just a subjective artefact, and would only have meaning for the individual as a sort of existential experiment/coping mechanism to an apparently absurd universe/artistic endeavor.
So either there is no purpose to life and there is ultimately no point to anything and the universe may just as well not have existed, or there is some objective purpose to the whole unfolding of life on earth, but this can never be known by anyone, at least not before death.
So, given our state of limited knowledge and relative ignorance, my subjective system of values is simple: just try to be kind (especially to animals) and try not to cause too much suffering for however long you have left in this universe, which I hope is not very long, as the bus is waiting. If there really is no purpose to the whole thing, I won't have lost much in just trying to be kind.
