Atheism: a strange, self defeating doctrine.
The word atheist comes from the Greek word “atheos”, meaning godless and therefore atheism is a philosophical or religious position characterized by disbelief in the existence of a god or of any gods.
Let us suppose for a moment there is no intelligence behind the universe; no creative mind; no designer. In that case, nobody designed my brain for the purpose of thinking and therefore it just so happens that when the atoms inside my cranium happen, in some mysterious way, for either physical or chemical reasons, to rearrange themselves in a certain pattern, this gives me, as a by-product, the sensation I call thought. But, if that is so, how can I trust my own thinking to have any validity or to be in anyway true?
It’s no different to hurling a handful of sand in the air and believing that when it lands it will form a meaningful, intentional and recognisable pattern, whereas that created, would, de facto, be irrelevant to all but chance. Therefore, if I'm unable to trust my own thinking, then I can’t trust the arguments leading to atheism, and therefore have no reason to be an atheist, or indeed to be anything else.
Unless I believe in God or a universal Creator/Designer of some sort, it is illogical to believe in objective thought and that being so means I can never use thought to not believe in God.
Our reasoning power is much more than cerebral bio-chemistry.
Atheism is therefore a form of reasoning that is self defeating.
