If we say that the Sun acts as a spotlight, it may suggest that it is a spotlight, and create a positive claim of what the Sun is. I would rather remove that implication and have them ask "How does the Sun do xx," so they can look further into that subject without that possible taint of information.
These were the changes made to the FAQ on this:
"It's also worth noting that if a person were to look down at the Earth from high above, they would expect to see a circular shape where the sun's spotlight was shining." --> "It's also worth noting that if a person were to look down at the Earth from high above, they would expect to see a circular shape where the sun's area of light was shining."
and under
How do you explain day/night cycles and seasons?"...When it is over your head, it's day. When it's not, it's night. The light of the sun is confined to a limited area and its light acts like a spotlight upon the Earth." --> "When it is over your head, it's day. When it's not, it's night. The light of the sun is confined to a limited area upon the Earth."
The text near the second modification does already give a link to the sunrise and sunset page:
"The picture below illustrates how the sun moves and also how seasons work on a Flat Earth. There are
several potential theories for the apparent effect of the Sun's rising and setting."
Presumably if they were curious they would click on that.
But yes, at some time in the future the community should probably generally concede that EA theory won among the FE sunrise theories and use EA as a major part of how FE is described. There is likely a better and more engaging way to explain it all.
