Life Proves Nothing

The argument in favor of the existence of a creator deity because the universe is "fine-tuned for life" is flawed in a basic way that should not be easy to overlook. We can pick any item or substance or system that exists and say the universe is "fine-tuned" for it, meaning the claim is literally pointless. Anything that exists exists because the conditions in which it exists allows for it. This is about as far from a special condition that needs a deity as can be imagined. If someone wanted to claim the existence of an entity with supernatural powers, an example other than carbon-based creatures that came about where it was possible needs to be shown.
