Hell. Even the New Testament with its Ancient Greek to modern Greek to English is pretty fubar. In even the Greek there are multiple words Christ uses for the very important term 'love'. Yet in English it is just turned into one word. And that's just the major one I can think of off the top of the head. Oh and then there's the whole "Upon this rock/Peter I build my church" which helped split the eastern and western Christian churches a millennium ago and had the Pope figure he was the head of the whole shebang. Not the only reason, but that was a scriptural basis hinged on translation.
Meanwhile.. maybe these aren't angels. Well.. they are.. but.. maybe they are.. fallen angels. In particular.. what if they are the many who are one? Legion, the demon(s) who were inside of a man and who Christ cast out into a group of pigs and drove off a cliff.
Also.. I am pretty horrified that evolution is only at 15% in this country. I thought we were doing at least a little bit better than that. Like Superman, I believe in all three. Well, maybe not quite aliens but at least their possibility.
And.. technically... if angels do exist.. they are aliens. Alien and extraterrestrial just means something not of this planet Earth, be they from another planet or a higher dimension.
