The children were either very young, or having a laugh when they echoed that God makes light bulbs light up! However, I haven't heard of any C of E schools which brainwash children into thinking that God does everything - certainly not in such a literal way! I'm not religious, but I can see a trend starting, whereby the very idea of there being a "God" is fast disappearing, due to scientific explanations. However, because there are many unexplained things in this life, and because worship brings comfort to those who wish to believe in a higher entity, who's to say that they're wrong?
