Forgot to add - I also reject completely your claim that science leads to nihilism. If anything, it looks like people who feel a need for some mysterious, supernatural (?) "purpose" are easy prey for nihilism. That's why such people must have unquestioned belief in unproven and unprovable things. I'm perfectly fine with questions and enjoying the most probable explanation: that there is no "purpose" to the universe, that the universe simply is, and that How does it work?" is a valid, productive question that leads to our betterment, unlike "To what purpose?", which only leads to unprovable, unproductive false answers.
