It would be the final blow to the theory of Evolution. The mathematical chances of life spontaneously arising from non-life just once are equivalent to zero. But if life or the former existence of life is found outside of this earth--then what are the mathematical chances of life arising from nothing (by chance), not once, but more than once?
2. If life is one day discovered to exist beyond this earth it will present no problem for the Christian, for God is the Creator of all life, both physical and spiritual (Colossians 1:16; 1 Corinthians 15:38-41).
3. The Christian already believes in life-forms from another world, i.e. God (2 Corinthians 13:14); angels (Hebrews 1:14), etc...3. Extra-terrestrial life has already visited this planet, the Creator Himself came and died for our sins (John 1:1-14; 3:16).
