Yeah,
Watched the video, it's amazing.

Our own existence in this infinite universe (or maybe finite, don't know) is mysterious. The origin of life is an unsolved mystery (also wrote an article about it).

Thermodynamics says that the purpose of life is to help the universe to increase the entropy and bring an equilibrium.

But, as said, we are probably, the only free thinkers who can act freely (unlike stars which are bound by the laws of physics) and maybe solve the mystery of the universe and probably one day control the universe to make an utopia out there.

Also a better way to do good to our existence is to help others, maintain peace and let the humanity grow upto that point when we will that much intelligent and capable to know about the universe and settle human civilization in its different parts and probably find other alien creatures out there. :D
