Some can do something 'referenced in the Bible" as ones who can involve angels in disguise as many records still today. They travel across the galaxy, or and some call them aliens from another world have sent AI over vast distances, what's so hard about believing spiritual entities from another dimension might appear in human form under God's direction? Hebrews 13:2 (various translations all say the same); "Do not forget to show hospitality to strangers, for by so doing some people have shown hospitality to angels without knowing it."
Additionally, angels of the Bible are spiritual beings who have personalities that include emotions (Luke 2: 13-14), intelligence (2 Corinthians 11:2, 13) and wills (2 Timothy 2:26). Satan was an angel who was cast from heaven along with many other angels who decided to follow him and chose to sin (2 Peter 2:4). In terms of free will, the Bible reveals this was an exercise of their ability to choose (Jude 1:6).

Working with Lorna Byrne and producing this documentary about her amazing life and gifts was truly an extraordinary experience. Lorna is perhaps the most honest and humble person I have ever met. She will say that she doesn't know why God chose her to spread his messages of love and religious tolerance, but I think God chose very wisely. Watch the documentary and see why millions of people worldwide believe in Lorna and her messages from the Angels.
