Morning Scepticism: Carbon

It's obviously true that the universe has to be in such a way as to permit our existence, otherwise we wouldn't be here to comment on it! Those who invoke the anthropic principle in evidence of a cosmic designer are merely pushing the argument from design from our biology to explaining biology itself. It's an argument that concedes that evolution works, but only because a designer made evolution. But I suppose they have a point, how else do we explain the size of a carbon atom without concluding that it's because God loves us?
