At what age should a child be introduced to religion?

[vulcanlogician]

From what I understand, logical thinking starts kicking in around age 12 so no earlier than that.

Around 12-13 is when I'd feel comfortable making the case how I personally feel about religion. But before then, the child is going to be exposed to religion in many ways. They'll need to learn the basic facts of it. So before their capacity for logic fully matures, I'd simply give them the facts about it, as impartially as possible, and let them make up their own mind.

When they're old enough to know I'm not any kind of authority on the matter, I'll let them know why I think it's bullshit.
