The odds that there is any life anywhere much less life like we have on earth much less life as advanced as cat much less life as advanced as humans are so small as to be almost zero. If science looked at it honestly they would say there's no chance. Honest ones who saw there's no chance then had to come up with and push the idea of a multiverse....now the thought is that there are an infinite number of universes where anything could happen and we just happen to live in one of the successful ones. Again, other attempt to explain our reality without turning to God.
God has divine beings (created beings) in what humans might call infinite numbers. The fact that the Bible doesn't describe everything about the heavenly hosts or divine or even evil spirits doesn't mean they don't exist.
As many theologians have said, God explains reality to us on a need to know basis.
Even all the things that Jesus did have not been disclosed.
As John told us (21:25):
Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.
It is always interesting how backward-looking men shrink God to justify their narrow thinking.
And these are not Bible-thumbing military men. These generals are saying that what we are dealing with conforms in general terms to what "might" have historically been thought of as Biblical demons. In other words, they appear to be interdimensional beings and somehow seem to have a paranormal element to them.
Many people who have been abducted by so-called aliens describe their abductions as a physical and spiritual "rape." Meaning their experience suggests that some of the beings are evil.
