Genesis 15:5 (NKJV) - Then He brought him outside and said, “Look now toward heaven, and count the stars if you are able to number them.” And He said to him, “So shall your descendants be.”Translation: there are a lot of stars up there.
Psalm 147:4 (NKJV) - "He counts the number of the stars; He calls them all by name."Translation: Considering what we currently know about the size of the universe (or at least the number of stars based on Hubble observations and other telescopes), that's a lot of names. To me, it would seem a bit strange to create so many suns and worlds without any life on them. Whether we can actually reach any of the habitable worlds or whether they can reach us is another matter altogether. It's quite possible God has placed each world far enough apart for some reason unknown to us.
Consider some more verses:
Psalm 8:3-4 (NKJV) - "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained, what is man that You are mindful of him, and the son of man that You visit him?"It is apparent from these verses that God has ultimate control over not only the Earth, but the stars themselves. To think that He could break apart constellations is nothing short of amazing, although it would make sense considering He made the stars in the first place.
Job 38:4-7 (NKJV) - "Where were you when I laid the foundations of the earth? Tell Me, if you have understanding. Who determined its measurements? Surely you know! Or who stretched the line upon it? To what were its foundations fastened? Or who laid its cornerstone, when the morning stars sang together, and all the sons of God shouted for joy?"
Job 38:31-32 (NKJV) - "Can you bind the cluster of the Pleiades, or loose the belt of Orion? Can you bring out Mazzaroth in its season? Or can you guide the Great Bear with its cubs?"
Again, though, I ask the question: are there Bibles on other planets? My answer is: why not?
Although this is only speculation, perhaps those Bibles even fit together with our own. As long as they are logically and truthfully consistent with what we have, then it is possible.
In addtion, throughout the Bible, God has this interesting trend of revealing more and more of His plan to us...whether it is in the form of temples, salvation, etc. Notice, too, how in Scripture the temples seem to grow in size and complexity as time goes on. For instance, comparing the mobile Tabernacle in Exodus to the temple built by Solomon to Ezekiel's temple to the New Jerusalem. Perhaps, then, too, there will come a day when God will reveal those other worlds to us and maybe with it that the Word truly is consistent...on Earth and everywhere else.
