I am 58, I have a vague memory of being lied too about Father Christmas , being told thays not true even though I was assured he was originally and then thinking the same thing about god (catholic family) but figured out for myself that it was bullshit. Doesnt take much ciritcal thinking, even as a kid to realise that.
I had to LARP for a bit but stopped the nonsense of church etc when I was allowed too as a young teen. Reading more widely after that you get to see some of the utter horrors caused by religion and release how toxic they are.
An example, lived in Cambodia many many years ago and a bunch of evangelicals wouldn’t let locals use a water well until they “converted”. A constant reminder of the toxic nature of religion.
