Not really, they'd just need to exist in a dimension above ours. We can readily observe the lower three dimensions of length, width and depth because we exist in the one above that - duration. We can't observe time except by passing through it point by point. A being capable of observing actual timelines would have to do so from a vantage point above them.
The extra eyes and wings are just them being a fucking showoff.
Or maybe a desert villager named Ezekiel with literally zero education and world experiences who was high on drugs saw a peacock which likely escaped from a local traveling merchant cage because those animals come from a fucking jungle, and the idiot couldn't explain what he saw and just attributed it to an angel because he and his religious buddies are all fucking stupid.
Why would the angel say "be not afraid" because he wants the predator to chill out and...eat them? Are angels piloted by suicidal, parasitic organisms forcing them to be eaten in order for the predator to spread more parasites?
Or maybe the biblically accurate angels all have really good eye spots as well that we just assumed were eyes and they are trying to scare off something even worse.
So if you want to slip out and really get crazy with those Canaanites you got to be able to cover your 6, and your 180, and your 278, might as well also cover your 112 too.
