"Why am I even here, what's the point?" is a deeply personal feeling question, so people aren't very inclined to talk about it with friends or post it on social media. I assure you some people do post about this on social media sometimes though, and I've discussed shades of that question with many friends over the years. I haven't yet met a single person who, when I asked them about why they thought they were here, hadn't already given it thought.

This question is the subject of so many poems, so many pieces of literature, so many movies, that you're forced to confront it multiple times in school, and you're forced by your very existence to confront it once you hit certain levels of mental development. You're forced to confront it many times in your life - perhaps first when you gain a theory of mind (before age 10), again when you first truly realize you will die, again when someone very close to you dies, when you propose/marry (if you do), when you have your first child (if you do), when you get a cancer diagnosis (if you do), when you consider taking your own life (if you do)... all of these common life events force you to confront it deeply.

Most people make peace with it in some form, and most realize that questioning it daily does not make a difference, you simply have to either accept an answer (whether that's "god", or "for no reason", or "I'm not sure yet, I need to check back in after I get older"), or decide that there is no simple answer, and they have to live with that.
