Well, why would there be a purpose to life? I'm talking about a rational, defined purpose. That's basically saying everything is pre-determined. Were all dead men/women walking and theoretically there is no scientific point to anything unless you believe in fate- whatever. Essentially, in my view, the entire universe begins and ends through your own eyes. This is everything, its your one shot to help advance human society in its quest to grow and dominate the universe.

But what is the point of the advancement of human kind? Well, conquering death is one thing, so is answering all of those great questions, but that's not really answering this question. Sooner or later we will all die no matter what tools we use. Someday all the questions will be answered. So there isn't really an answer to this question. Its just what we are given with. But as long as you have the want to live, you inherently want to help this cause to further advance society since you obviously care about something. So basically, being human (Following human wants and needs) and helping others in society is the point of life. Now, people that still don't see a defined purpose in life from what I said don't want to be human. As in, you wan't to be dead. Dead, dead. Universe is essentially gone dead. And that's not fun is it?

Tl;dr: Being human makes our perspective on the world inherently skewed with things like emotions, so the point of life is fulfilling these emotions that drive us to advance society.
