To whom? This is your same specious definition of 'purpose'. you're not defending it; you're simply re-asserting it. Do you now why you're unable to defend it, but must simply reassert it? Because there is no such thing as an objective purpose. Purpose is defined by humans and there are seven billion humans who each do that individually. No one is more right than any other. (Though some are more wrong than others. Namely, those that overreach their ability to assert. They are *provably* wrong).
