[Just reporting]
Here are some comments from the WT pubs...why no life now...but can't rule out life later (space travel...through angel power?)

What About Life on Other Planets?
Some influential religious figures have insisted that God would not create any world without purpose and that all habitable worlds must therefore be inhabited. Is that what the Bible says? No. The Bible indicates that it is very unlikely that God at this point has created intelligent physical creatures on any planets other than our own. How so?
If God did create such beings, he did so before he created Adam and Eve. Such beings either remained faithful to their Creator, or like Adam and Eve, they sinned and fell into imperfection.
But if they became imperfect, they needed a redeemer. As one essayist put it: “One has this dreadful thought that on Friday [the day Jesus Christ was executed], every Friday, somewhere in the universe Jesus is being hanged high for someone’s sins.” But that is not Scriptural. The Bible tells us that Jesus “died with reference to sin once for all time.”—Romans 6:10.
What if these beings had remained perfect? Well, when Adam and Eve sinned, they were, in effect, questioning God’s right to rule over a world of intelligent physical beings. If another planet existed at that time, a world full of intelligent physical beings who were living harmoniously and loyally under God’s rule, would they not have been called in as witnesses to testify that God’s rule does indeed work? This conclusion seems inescapable, since he has already used even imperfect humans as witnesses in his behalf on that very issue.—Isaiah 43:10.
Does that mean, then, that God created all those countless millions of suns (and planets if they exist) for no purpose? Not at all. While we know, considering the uniqueness of Jesus Christ, that the earth is the only inhabited planet in the universe right now, and while we know, too, that it will forever stand unique as the planet where the Creator vindicated the rightfulness of his rulership, what the future holds we do not know.

But what about the other planets? Were they put in space and into orbit for no reason at all? No, we cannot conclude that. All that God does has meaning and purpose. Obviously the Creator Jehovah God has a purpose for these planets, including the planets in our own solar system. In time, he may well reveal that purpose to obedient mankind. We should not be so shortsighted as to think that the earth is the center of the universe.
