I pretty much went through the same thing when I was a kid. My mother sent me to religious school, and they talked about God all the time, and also talked about all kinds of laws and traditions and religious practices you have to constantly be aware of. None of it made sense to me. I didn't see any morality in the teaching and following rules didn't help life on Earth, so how was it good? The whole unworldly aspect of religion it such nonsense to me. By the way, I'm also an engineer.
