Globe model includes Universe.
Flat model denies it.
Globe model claims that at 2.537 million light years away is Andromeda Galaxy.
Flat model claims that Andromeda galaxy doesn't exist that way.
People who know Flat model well would know what exists at 2.537 million light years from Earth.
If it is not Andromeda galaxy, then what is there instead?
Globe Earthers, please don't pretend that you know what Flat model says for such distances. What you know is from Globe model.
Flat Earthers will know better what is there in Flat model.
This question is for them.
