So you're saying that there cannot possibly be any other purpose in our lives outside of biology because we have a lot of DNA in common with monkeys?
I just don't see how that follows. It's like saying "computers are useless for any applications outside of pure mathematics because every operation a CPU executes is mathematical in nature" or something.
Humans are nothing but hormones projected onto physical world. Expanding in space and time is a task of any living organism, be it your genes, ideas, etc. I won’t say more.
