I don’t think there’s some special reason for living or purpose in life that’s given to us when we’re born. As we grow and mature, I think we develop our own purpose for living. Of course not everyone does, which accounts for people committing suicide on the account that their ‘life has no meaning or purpose’.
Humans were not put here for some grand scheme by a sociopathic, all knowing, all powerful god or gods. The universe may be infinite, and if it is, then there’s no reason to believe we’re the special ones. With all the wonder and amazing things out there, there’s literally no reason to ever believe we’re special because we occupy this infinitely unimportant speck in the cosmos.
In short, I make my own purpose in life, no one else does.
