I’m an atheist and secular humanist, and I’ve been asked for my ideas about the purpose of human existence. I think there’s no innate, biological purpose beyond surviving and reproducing. Humans are the fortunate result of billions of years of evolution. The more we learn about our natural world, the less significant humans seem to be. Charles Darwin showed that we are all animals in a long evolutionary line.
But purpose for humans is about more than mere surviving and reproducing. It’s about what we believe we should do in the brief time we’re alive. To have purpose, we need goals and plans that give us direction and meaning, and helps us engage in productive ways. I believe we each need to find our own purposes. For example, my wife Sharon has a T-shirt that says: “Be Good, Do Good.” She says that’s her main purpose. I know and respect many fine religious people, certainly including the folks here. If loving & worshipping a god inspires a person to treat others with loving kindness, that’s great. Unfortunately, love of a god can often make people less loving of those who don’t believe & worship as they do.
