I don't think so necessarily...
I mean, the Bible doesn't say there aren't other realms in the universe where life exists...it just tells us that Earth is the only place where humans can live. Frankly, we have a hard enough time dealing with other humans - imagine how much we ain't ready to deal with non-humans!
But personally, I have not ruled out the possibility of "something else" in the universe...the parts in the Bible I think of in connection with that idea are:
- In Genesis where they defy the command to spread out to inhabit the Earth, and instead try to build the Tower to the heavens...God put the drop on that
- Jesus told the Apostles "I have many things to tell you, but you aren't ready yet..."
- Revelation says Earth will be cleansed and "new scrolls will be opened". Might be some scrolls talmbat "Aight, if y'all act right for a little bit, we can get some more planets to visit..."
