I think the assignment was to teach critical thinking skills. the problem is that the teacher probably a atheist and used the assignment to impose her belief system. The mistake that was made was using a religious belief system as a test on whether someone knows the difference between fact or fiction. A better question would be stage magic real or not real. basically the idea was to teach logic skills to young children.
“I think the assignment was to teach critical thinking skills.”
Then, the teacher failed the test.
The existence or non-existence of God cannot be proven or disproven “scientifically”. It was wrong to assert that the existence of God is a myth — because the teacher has no way of disproving the existence of God.
Except the questions were around God and America - which immediately sent up a red flag that this was not about logic-teaching but, of course, indoctrination. Or undermining a child’s belief in a supernatural being and his faith in his own country. Undermine those and you have the potential for a future bad citizen. Just like those brats at the U of Missouri.
