Why would it say that? Do you know any aliens? If not, then why would it be our business. Why would we need to know?
Ok, lets go further. The Bible says that man fell into sin. How do you that if there are other worlds that they fell also? You assume that the universe centers around the Earth, and in our minds it does. But the truth is that we have no idea what the universe contains....or what is beyond it for that matter.
God is not obligated to reveal the secrets of the universe.

The bible says ALL have sinned and fall short of the glory of God.
Colosians 1:13 Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
14 In whom we have redemption through his blood, even the forgiveness of sins:
15 Who is the image of the invisible God, the firstborn of every creature:
16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
17And he is before all things, and by him all things consist.
18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
19 For it pleased the Father that in him should all fulness dwell;
20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.
21 And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled
22 In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:
Philipians 2:6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Hebrews 9:11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
These all seem real clear that Christ taking on the form of man became payment for man's sin, animals blood could pay the price, their blood was merely a covering. Christ had to become one of us to pay for our sin and yet scripture says His payment was "...by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven..." and yet He never took on the form of an alien being other than man being alien to Him and He must take on that form. God made it abundantly clear that Christ reconciled all things, in His death, Salvation comes by Faith in Him as the God-Man, not the God-Man-Alien.
