This is the mindset of a believer. Guess what David T? My happiness does NOT depend on invisible forces. It is a testament to your foolish mindset that you think I have traded one set of invisible things, like demons and angels, for others, like bacteria.
Hey Dummy! Get a microscope! Bacteria are not invisible with the right tools! In fact, whole genera have been classified, and many species within those genera! The taxonomy of these "invisible things" are so consistent that thousands of different people have independantly identified them repeatedly!
Not so with demons and angels.
Ask a Mycologist about fungi, and you get the advice of an expert. Ask a priest about demons, and you get the ramblings of a con artist. They are nothing alike.
I don't need invisible things to be happy. I am content with what I can regularly accept to be true about me and the world around me. Mister Egnor, next time speak for yourself.
