The point of life?

. . .
Your friend sounds like the kind of person who would harass me for being an atheist. I'll spare you what I was originally going to say, it's quasi-off topic.

Actually i'm kinda atheist but we still became friends. He invited me to go to church many times already, and i denied it. (I've been to church before, with my parents cause they are kinda Christian, and I can't stand those people crying in the church for no apparent reason.) He said that not all churches are like that, the church i'm going to don't cry. but I was like what's the point of wasting every day of the week doing something boring, or praying to god like 3 times a day? (he prays before he eats lunch, so I assume he prays when he eats breakfast and dinner too) anyways I show him this youtube video,(a video similiar to this one, I think the one i showed him got removed

and after that he just said god forgive his sin! Yea sometimes he pisses me off big time, but I still need him to do my math and physics hwk >.>
