How come every time I ask a difficult question I'm being called a moron by the Atheists?

To answer your question from our veil of perception, we have the tools, science and technology, to explain life on earth and how it could possibly exist on other planets. What we are ignorant about is the fact that life could exist in forms we are unfamiliar with, so we tend to exclude the possibilities of life existing by other means (not rocks, or other common sense things, however). This could include anything from organisms that survive on elements that are unheard of to metaphysical beings. In any case, we haven't yet come across these other forms of life, so it is easy to say they don't exist.
