We can probably all find out why we are individually here. Why our parents chose to reproduce. We are here thanks or no thanks to their desires.
Life as a whole? I just tend to believe it evolved to be like this. It maybe just happened that there were the necessary elements on this planet with a temperate enough climate to allow for life to generate. I suppose chemical/ biological reactions to begin with, that then evolved over billions of years- each organism adapting to suit its environment till voila- all that we have now. That's my feeling.
I'm really not sure whether there's spirituality or a God behind it all but, I'm hoping not. It would deeply concern me to know that all of this was built with intention.
Because it's so unavoidably sadistic in many ways. I'd prefer it if it were all chance- then, it's only unconscious, indiscriminate bad or good luck- depending on your circumstances.
Of course- it isn't indiscriminate when it comes to humans. Would- be human parents do have the capacity to judge what kind of world this is, how good their genes are, how stable their finances look etc. They could have at least tried to predict how our lives would shape up.
I just think we try to find meaning as a coping mechanism because life will likely be difficult and painful at times. It can help to feel like there is at least some point as to why we're putting up with it all. I think that can feel very real to an individual but I doubt there is an overall meaning.
I'm probably the closest to absurdism in terms of philosophy. I even like the word as a description. I think life is absurd. We end up working so hard and, for what ultimately? I guess the ideal is to make it feel worthwhile. I think that can be worth at least pursuing- if we're stuck here.
But, life at it's worse is a trap I feel. An emotional entanglement that our parents tie us up in that we then have to suffer guilt or bereavement to break- depending on who goes first. Maybe for others, it is a gift but then, who would play the lottery if there were (deeply unpleasant) boobie prizes too? You either win a million or, someone comes round and breaks both your legs. The unfairness about birth is parents leave it to their children to face those highly variable odds.
