Off-topic but if you don’t mind me asking, how did you parents answer big questions like on the origins of the universe? Did they tell you religious people were wrong? (my religious parents go out of their way to differentiate us from ‘them’ so I’m curious.)
Some don’t have an answer or don’t care. Some parents show all the religious answers to disillusion the uniqueness and originality of major religions’ answers. Many children don’t ask or care. Many children are perfectly fine with documentaries about the Big Bang, seeing the complexity involved.
I asked, my parents didn’t know and cared little to find out, I found documentaries and audiobooks made for children. It took a long time for me to understand that the boring religious stories they subtly taught in school were seeking to at least partially replace the scientific narratives.
We were/are always just honest with our kids. No, we don’t think there’s a god/goddess/whatever. When we/grandma/grandpa/whoever dies, they’re just gone. Nobody knows where the universe/world comes from. As far as anyone knows it’s several billion years old. Explain the big bang as best as we know it. Etc.
There’s no ‘right’ way for so many things when it comes to kids. Ours know that many people believe in a god. We don’t. That’s ok.
