Why would God engineer giving an embryo teeth that are not needed? That is assumes God is a moron. I don't like that assumption.
1 John 2:18-21
Warning Against Antichrists
"Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour. They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us.
But you have an anointing from the Holy One, and all of you know the truth. I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. Who is the liar? It is the man who denies that Jesus is the Christ. Such a man is the antichrist–he denies the Father and the Son."
You will be called the Antichrist for that one.
