What does your faith have to say about other biological life in the universe?
Does your faith teach we are "alone," so to speak, the only planet in the universe to support life?
Or perhaps it teaches there are many other planets with life?
If we discover life on other planets, would that change your religious view in some way?
The Bible while not making mention of life elsewhere in the universe, apart from the spirit realm where Jehovah God lives with his firstborn son Jesus and other spirit creatures in his likeness, does seem to indicate that as of now earth is the only place with intelligent life.
This is seen in the fact that an angelic son of God rebelled against his Sovereignty and had the first man and woman join in.
The fact that this was unprecedented and precedent needed to be set, especially when Satan makes the claim that everything a man has he would give in behalf of his soul, along with the fact that Jehovah is a liar, and not a good Sovereign, and Jehovah allowing the rebellion and time for Satan and rebellious humans to show whether Satanic rule, or human rule apart from God rule is better, would indicate that we are currently the only planet with such life that the issue could and is being settled on. (edit - what do you think of this run-on sentence)
If there were other worlds with intelligent life God would not need to point to humankind, and earth would not be the focal point of the universal issues that Satan and other rebellious wicked angels raised when rebelling.
The rebellion has been only around 6,000 years out of the 13.8 billion year life span of the universe (not to add in however long Jesus and the rest of the spirit-realm existed when God created them.
So evil has only existed a very short time-period in the scheme of things. The Bible says that a thousand years to us is like a day to Jehovah. So for him not even a week has passed since man was created and the issues of his universal sovereignty have been raised.
Things are coming to a head and soon Satan and his wicked angels along with their rebellion will be completely crushed and put out of existence now that the court has had enough time to prove the uselessness of Satan rule and man rule.
In the future, if life is ever created elsewhere, or even if life here chose to rebel again, or in heaven, the precedent of Satan and his rule along with wicked humankind that will be destroyed will be an example forevermore of the effects, and God will no longer need to tolerate evil. The rebellion will simply be put out of existence.
Holy scripture says that those who are called to heavenly spirit life from earth, adopted as spirit sons of God and brothers of Jesus Christ will reign as kings forever in heaven, and that they will judge the angels. Thus they will forever be there to judge in the future if anyone anywhere wants to rebel. They will be eye-witnesses both of the outcome of rebellion against God's good rule, and faithful examples of imperfect humans that loved Jehovah more than their own lives, proving Satan the liar that he is, all 144,000 of them will have been obedient under test until death, thus being rewarded with immortality and incorruptibility (something Satan and the angels were never created with or given).
