to bring to pass the immortality and eternal life of man.
Through the resurrection of Christ, everyone will be resurrected and become immortal. Through the atonement of Christ, everyone who believes and accepts Christ and follows His laws and ordinances will receive eternal life.
Agreed, so where does this address any life forms that are not-man or of extra-terrestrial flavor?
It doesn’t. Not saying there is, or is not ET life; not saying that God did or did not Create there also, just that He did not address it in the Bible and that it is presumptuous to say, outside of what He tells us, that we know His ‘motivations’ in reagards to it.
