Yes, the elements are eternal, intelligence is eternal.
That which has a beginning must have an end. You hold up a ring. It has no beginning and no end. It is in the likeness of eternity, one eternal round. Cut it, and it has a beginning and an end.
God will give all of us immortality in the resurrection. Immortality has no end. He will give the faithful eternal life, which has no end, and it follows therefrom that our existence had no beginning either.
