Thank you for covering this very interesting and important topic. As a Christian, I struggled to make sense of this very thing, ET's, what are they and why doesn't our church leaders ever cover this strange but critical area? In trying to find answers, I read many books that were interesting, but never could agree with entirely with the authors. Finally, I found a book "The Unseen Realm," by Dr. Michael Heiser, a biblical scholar and a expert on many extinct ancient languages. He explained how we, Christians especially, miss what the Bible saids about this topic because we're not taught to understand the Bible textually as scholars are groomed to do. After reading Heiser's book, I am beginning to see the light of what the so-called ET's are, and how the Bible explains this. You can find many of Dr. Heiser's discussions on youtube, which I highly recommend to anyone who would want to know this in the Biblical context.
