If the sun was local wouldn't the shadow also be different at different places?
Discussion
What do you mean local here?
I suppose much depends on the agreed/assumed size, energy, and distance of the sun.
If the sun was smaller than the moon and just miles above the disk-like Earth, then yes, shadows would vary regardless of position.
That still requires a hypothesis as to how parts of the disk were day vs night, and the path the sun and moon would follow to facilitate this.
It's a good meme. My thoughts below.

Local meaning a few thousand miles above. Maybe the earth is electromagnetic and the sun and moon move like the hands of a clock.
Is the sun round?
Don't know
I'll try and find out what flat earth theory suggests in this case. I agree that if we are fundamentally wrong about things like the sun's size, shape, and distance, then alot of theories about the known universe are no longer valid.
