Have You Ever Seen An Angel?

Have you ever sen an angel?Do you know anyone who has or know anyone who knows anyone who has?The answer will be invariably no.So where all the angels and why do those that supposedly appear only do so in the middle of nowhere?Why not in times square where we can all see them?The same goes for flying saucers why are they all in Outer Mongolia or some other out of the way place but never seen hovering over the white house.When these angels do supposedly appear why don't they tell us something useful and difficult like how to cure cancer not what people should wear and eat which any good playwrite could come up with.Angels if they do exist will know how to cure cancer because after all they are sent by god and he by definition would know how to do that.So why did'nt the angels tell us something simple like there are nine planets or perhaps the periodic table or some relativistic transformations.They would know these things so why did we have to wait for Mendelev or Einstein.There are many things that angels could do to prove their existence but don't and why.The answer is simple and that is they don't exist!It strains credibility in the extreme to believe in them and the proof should be on the people who tell us they exist to actually produce one and not give rationalizations as to why they don't appear or even tell us something verifiable about the world. If someone is going to make a preposterous claim they should prove it.
