Here is the second chapter of Luke:

Luke 2:8-15. Clear situation of the coming of 1) a physical angel, 2) a physical mothership (why would they be afraid of the glory of the Lord, otherwise?), and 3) a physical spaceships fleet ('a great company of the heavenly host').


Now, John and Acts 1:

John 20:11-12. How could they be more physical?
Acts 1:17-20. How did the angel open the doors of the jail? So, here is the answer:
Acts 12:7-11. EXACT PROCESS OF THE MODERN EXTRATERRESTRIALS' ABILITIES HERE.
Acts 12:23. Is there a more physical interaction than the death given to someone?
