Actually, I CAN tell you the majority perspectives of Pentecostals on the topic. They cluster roughly as follows:Sorry didn't see this one before replying above -- however, NOTE, you gave me PERSONAL opinions, and I'm guessing that if you polled Orthodox, Lutherans, Catholics, Presbyterians, BAptists etc. there would be numbers who fall into the three viewpoints you described.
A) DENIAL--nothing going on. I'd guess 40-60% hold this perspective.
B) It's all 100% demons. Some insist the craft themselves are actually demons morphing deceptively etc. I'd guess 60-40% hold variations on this perspective.
C) A small minority may hold curious idiosyncratic perspectives.
You are not asking me but I am responding, honored as I am to be included in your post.
Inasmuch as the Word tells us there are two kinds of created beings, angels and humans, and the aliens are manifestly deceptive, then any alleged ‘aliens’ would have to be fallen angels.
