The thing that tickles me about atheists, is that the mock us for our 'faith'...for believing in something we can't see or know absolutely. But the thing is, they are living under a belief system that is not unlike our own. They say 'science' is their guiding star, but there are many things in science that have to be taken in faith. Basically, they are swapping the word 'faith' for 'theory'. Science has things that function on theory alone...things that they really can't know is true. So, if they want to question Christianity, fine, but they really shouldn't be so silly to make a lot of the claims they do!
