Just to be clear...you believe that the sun, on its own, is somehow changing the size of its circles over the flat earth.
There is absolutely nothing known to mankind that supports that belief. Not in science nor in
religion.

This “geocentric” view is still held today by a few people, although Scripture does not require it and observation clearly shows the earth’s movement. The earth revolves around the sun once a year. It also rotates on its axis every 24 hours.
So, if your beliefs are not rooted in science or in religion, what is the basis for your belief that the sun makes circles (spirals) over a flat earth?
