To search for the meaning of life is to assume there's an answer but the question is our invention and meaning is what you make it. Encoded is our use by date to procreate and die, because evolution needs your space for the experimentation. Evolution is why we're alive, but the meaning is what you make it. Do you need 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.
