The day is soon coming. Satan and his fallen angels however are going to play on this as it's obvious that Satan created such lies. Some are good looking-stunning to view. Some have appeared as hybrids-smaller than the full fallen angels. The hybrids shapeshift dramatically.
Demons are minute compared to the fallen angels-fearful but more irritating than anything.
The world has no clue what they are in for. If you research the history you will see that in fact all through the millenniums there were gods and goddesses that looked like what we know as aliens-even UFO's. It's in caves, rocks, walls, pottery, religious architecture, etc. They were giants just as the Bible says. It is no surprise.
