Genetics urge all animals to meet, greet, and mate. This is true of birds, mammals, reptiles, spiders and people who believe that religion is just fairytales and fan fiction.

However, life is not all storm clouds and meadow muffins: we make our own purpose. We can choose to make more happiness in the world; choose to contribute to humanity’s progress. We can look at morality in terms of how much happiness we create, or how much pain and suffering we can wipe from existence.

Renown astrophysicist Neil deGrasse Tyson shared his purpose:

I remain unconvinced that anything other than rapid decomposition is the fate of my body and mind after death. I've accomplished enough in life so that I do not fear death. In fact, I've left instructions for my epitaph—a quote from the educator, Horace Mann: “Be Ashamed to Die, Until You Have Scored Some Victory for Humanity.” That's the creed I live by. And will die by.

This set of ethics, philosophy, and morality is called Secular Humanism. Secular humanists act in ways that promote the happiness and well-being of everyone. They believe that there is no god to save humanity, so humanity must save itself.

That is a noble purpose.
