The Creator can be found by studying creation and His Book. The nature of 'angels' has not been elucidated by Allah but forces of nature are one part of what they are. Another 'angel' is the means by which Allah communicates with man, since direct face to face contact is impossible.
Man brings the Creator down to our level, we try to understand Him as a father figure in heaven with His feet on a footstool and this is the same for every notion in the Quran that requires intellect and reason to work them out, not fairy tales.
It is easy to see the invisible when it is not there, look at UFO’s, a believer in them sees an object in the sky and says “martians”, a plane spotter sees a stealth bomber, an astronomer sees a planet!
Muslims have a load of preconceived belief that clouds their judgment when reading the Quran. Hans Anderson teaches us that all that glitters is not gold; all that we are told to believe in is equally suspect.
