All interesting but irrelevant to the fact that in Joshua the Bible says the Sun move around the Earth. If we are to accept the Bible as the literal truth, as young Earth creationists would have us do, then the literal fact is that astronomy is wrong and it is the Sun that is moving and not the Earth. So it’s not hard to believe that a good percentage of the people the story speaks of would be of the YEC variety.
That is almost certainly the case. However, I believe Scripture is literally true when viewed from the reference frame of the folks who recorded it. (Hence the "galaxies" questions.)
Even if the universe were revealed to them as a vision, they had no way of comprehending or recording what they were shown.
We have no such excuse. View this little video:
