Atheism the unscientific belief (part one, two, and three)

Little Rik is still here to show that atheism is 100% unscientific.

Per the third definition: atheism is, in fact, a body of knowledge on the subject of disbelief in god. So according to this particular definition, atheism can actually be classified as scientific.

I do admit that atheism does not fit into the frame of the first definition, though. You cannot observe or test the fact of disbelief in god.
