The word is spelt exist!!!!! You're obviously not making a typo, so I wanted to point that out so I don't have to look at "excist" every time you post.
You're clearly wrong and clearly won't be convinced because you have a dogmatic belief that we are here for the purpose of sex, so instead of trying to convince you, I suggest you read some books about evolution. Probably the most highly regarded book on the subject (apart from Origin) is The Blind Watchmaker by Richard Dawkins (which I haven't read yet, but have on my bookshelf). It's obvious that you've never studied evolution, so instead of debating this issue, I suggest you try to learn more about the subject, at least so we can be on the same page.
Apperently I know more than you do. I thought with your books you would be smarter.
I dont mean we are here to hump and die. You obviously have some other stuff to do while you live ( duuuuh ). But thats something you decided yourself ("I'm gonna be rich!"). Thats a personal issue. The goal of our species is to keep existing, like you said earlier: We exist because we are good in it, so we keep existing.
But YOU as an individual can't keep existing, so that cant be the purpose of life. So that's why we reproduce.
Saying I wont have children for this or that is again just a personal issue.
Like so.
GET BORN --> GROW UP --> REPRODUCE ---> DIE
Anything in between is what you make of your life. And i suggest that everybody should make the best of it.
