What's the point!

Why is there a Sun?
Why are there galaxies?
Why is there an earth and why are we here?

Why are there senses?
Why are there emotions?
Why is there love and why is there hatred?

What are atoms?
What are cells?
Why is there life and why is there death?

What's simply the point?

All of our actions are ultimately headed towards answering these questions. I think the world will end the day we find out the answers because there will be nothing else to live for.
