IF there was such a thing as life on any other planet, I might have to agree with your second point, but I seriously doubt it. “If” is a small word with a very big meaning. IMHO, there are no other human or human-like creatures on any other planet in the entire universe. Go ahead, call me crazy. You wouldn’t be the first.
Actually, it wasn’t only mankind that was tainted by the fall. The entire earth was also affected. All of the plants and animals, and even the earth itself, was twisted by the evil corruption of sin. I have no doubt that the effects of it also stretch across the entire universe.
“Genesis 1:  And the Lord God said to the serpent: Because thou hast done this thing, thou art cursed among all cattle, and beasts of the earth”
In this passage God curses the serpent along with “all cattle, and beasts of the earth”. Before the fall, all of the animals were docile and lived peacefully in the Garden, together.
“ And to Adam he said: Because thou hast hearkened to the voice of thy wife, and hast eaten of the tree, whereof I commanded thee that thou shouldst not eat, cursed is the earth in thy work; with labour and toil shalt thou eat thereof all the days of thy life.  Thorns and thistles shall it bring forth to thee; and thou shalt eat the herbs of the earth.”
But, in this passage, God clearly curses the entire earth. The curse affects the weather and everything else that happens on the earth, and to the earth. The corruption that’s caused by sin doesn’t only effect the person who commits it. Every single sin affects the entire creation of God, just like throwing in a single stone causes ripples that can spread across the whole pond.
Sin is like a cancer that will continue to grow out of control, without any chance of a cure, if it’s left untreated. As it grows in one place in the body, it slowly spreads itself to another place, and another place. It twists and contorts all of the cells that are affected by it, and it grows stronger as the “host” grows weaker. The end result is the death of both the “host” and the cancer. It’s complete chaos that just seems to charge headlong toward its own destruction. That’s what sin does to all of us, whenever we allow it to control us and don’t try to avoid it, or treat the infection with an effective remedy (Reconciliation).
