I can have a "personally-given subjective" meaning for my life, but from God's point of view our survival and existence is neither good nor bad. I would love to keep on living and propagate the human species, but that's strictly from my own perspective that may be shared with many other people. Shift the perspective, and it becomes impossible to ascribe "good" or "bad" to any of your or my actions. Whether the humans can colonize Mars or destroy everything with nuclear weapons, it's all the same.
