I am happy to see all the conversation my original post started! I have to admit I will need to reread the posts. I do plan to utilize all the info:)

MON- I have to admit that I agree with a lot of what you have said. I want my boys to learn about Catholism, so they will question and have to work things out. I also, liked your thought (simplified) of explaining how god made us and we cannot understand everything.

Aquinas- thanks for your references. I will look into these. At this point, ds mostly wants to know why. Why did god choose the make things the way they are? Specifically, why man and woman? (He knows things need to be that way to have children and continue civilization.) then he asked, why didn't he make the way we have babies differently? And specific details about how long did it take god to create earth vs. mars?

When my ds was 4, my grandfather passed. So, at that time he was very interested to learn about heaven. He especially wanted to know why he couldn't go.

Otherwise, in relation to religion, he believes what he is told. He is comforted by God and "Grampy" watching and protecting him. Yet, I am sure there will be more questions.
