You're right. The earth is clearly flat and that is a sensible assumption if you haven't left your local area or been in space or seen a picture from space.
Or not. Flat earthers are quacks.
It is the same principle essentially. It is illogical to think "hey if I keep walking that way I'll hit a wall eventually". That is why flat earthers are quacks from the beginning.
The same principle applies to space. What quack seriously thinks that eventually there is just a wall in space or that it wraps around?
Wrapping around makes zero sense in 3-dimensional space.
