Sorry, but you can't really exist here without benefitting from thousands of years of human effort offered up to you by our ancestors. Your ideas, your choices, your work, everything that you might consider a part of you, is a natural consequence of exposing the same basic machinery to a some combination of pre-existing material.

You are an emergent phenomenon - to claim "ownership" of anything is pure hubris, and reflects a dangerously limited understanding of causality.
