To search for the meaning of life is to assume there's an answer but the question is our invention, so meaning is what you make it. Encoded is our use by date to procreate and die, because evolution needs space for experimentation. Evolution is why we're alive, but the meaning is what you make it. Does there need to be a reason?
Life is a rental, it was never ours to keep and death is but the price to pay for borrowed time when you have no coin for more.
