I need to ask, does anyone else constantly compare themselves to everyone else resulting in feeling inferior to everyone else? I know I go on about that a lot, just curious if anyone else has a huge problem with that. Probably not.
Why is there cancer? Why does Jupiter exist? 'Why' can be asked for nearly everything. The answer, just, because. Why is that not good enough? Maybe, just maybe, we have no grand purpose. We are tiny little ants on some rock in a vast universe.
Yet cancer is killing millions of people every single year. Your view is insanely narcissistic, whether you know it or not. There is zero proof that we have any purpose other than just being beings in a evolutionary chain.
