I 2nd this :)

According to that Descartes troll, the purpose of life is to find out whether we exist when we're not thinking(conscious).

euft that doesn't sound good, why would you want to end your life?

To reproduce (to continue your family game/genetics)

But more broadly, to live a long, fulfilling life.

Worse than the purpose of life is the purpose of this universe.

What purpose does it serve? Why does it exist? The answer is that it just does. Its a cruel, terrible joke of existance and non-existance. Just like we have universe now, we had none before it. Its a chaotic existance that quite literally farted some reality, but it will not sustain itself.

The fun is discovering and trying to escape it as products of it. Maybe that is the purpose of life, to help your species escape its looming demise. Of course, not all of us can do that, so i recommend living life to the fullest while you can, find happyness. Individually we are as important as an ant we step on the street without realising.

There is no purpose of life since we made up that word and life existed before we did .

Thats what i call an epic troll!

You see you made one but quite big mistake. You can't ask from him to "prove" that God didn't existed since he isn't one making any claims in that regard. You on other hand did. And as such the one that is supposed to provide proof is you.

well logic also tells you that nothing created can exists without a creator
