it is weird how on some days you can see the moon and on the opposite side you can see the sun

from a flat earth perspective its easily possible to understand but from a round view it gets harder to imagine

also, the in the flat earth view, the sun is a lot smaller, so therefore, it would not be daylight always because the furthest away place from the sun, has lots and lots of atmosphere before it and the sun, thus the sun would be blocked.
