Phillip - A really interesting subject! I had never given this much serious thought, but since reading this thread, I find myself with certain ideas about this:
1. No, it would not impact my faith in any way. God is taking care of us in the way we need and that is all that matters.
2. For those that mentioned the lack of biblical references for this possibility, it seems to me that the Bible was written for us - not angels, not demons, and not any other possible creation of His. He does not provide us with everything He knows and does - and why should He? We cannot understand Him completely in this form, but He has given us His words for our earthly life. The Bible was not intended to be a reference library of everything he has done, just a guide for humans to return to the loving relationship He always wanted us to have with Him.
3. I do not live in fear that there are, or are not, other intelligent creations of His "out there". If they are there, He put them there. If there are no others, then He knows why not. We live in His universe, and as a daughter of the King, I trust Him to always know what is best.
