I am an athiest while wife believes in god. Problem is when she wants our 4 yr boy to believe in God and Temples. Talking to her hasn't helped either. Poor child is being fed with unscientific and centuries old fictitious lies! What to do?

I don't think it's a bad thing to teach your child about god and culture. I personally think that teaching them at a young age is alright and once they grow up they can make their own decisions on whether they want to follow or not follow the path your wife has chosen. However you should sit and talk to your wife about not forcing religion on them but instead just making them aware of it.
