When installing drywall, does one hang the ceiling material first or the wall material first? Or does it matter? Please explain.?

Update: Well, I believe that Mountain!! has the best explanation, although Jimmy C basically answers the same thing. Mountain answered first though. The reason I believe that one should ALWAYS do the ceiling first is explained here: https://diy.stackexchange.com/questions/...
Update 2: If one lives in an earthquake area, a ceiling that is not supported on its sides by wall material will most likely shake itself down. It drives me nuts to watch the TV show "First Time Flippers" and see the amateurs putting the walls up first. I would not want to live in that house ...EVER!
Update 3: Here's another "how to site": https://www.popularmechanics.com/home/in...
Folks that put the walls up first actually make more work for themselves in the end!
