Alleged aliens live on another planet. Fallen angels are not planet based like you said. There is required more than 800 variables for life to exist on another planet. There is not enough planets in the universe for that to happen. The odds are astounding when you get into each of those variables and multiplied together. You can plead no contest. Enjoy the majesty of the universe while not forgetting to achieve our full periodic table of elements required the universe be this big. It's that simple. Alien diversions is a waste of man's mind.
