“What is the purpose of life” is obviously not a stupid question. It’s a very good question.
The purpose of life is more life.
All life is purely trying to create more copies of itself. The purpose of every living organism on this planet (yourself included) is to create as many copies of it’s genes as possible.
That is all.
That’s not what you meant right? What is the deeper purpose of life? What is the meaning of life?
That question is actually a lot like “What is the square root of a tomato?”
It doesn’t make sense.
There is no deeper purpose of life. Life just is. It is a bleak realization, but that doesn’t make it any less true.
I was recently reading the preface to Richard Dawkins’s Unweaving the Rainbow which contains this excellent quote:
Gone is all purpose; all that is left is direction. This is the bleakness we have to accept as we peer deeply and dispassionately into the heart of the Universe.
