According to FEers, sunrises and sunsets only look the way they are due to perspective. They say that the sun only moves further away and looks like it is dipping below the horizon. So, if that is true the sun would always be above the clouds and never go below them. However, the sun does dip below the clouds during sunrises and sunsets. There have been many observations of the sunlight shining UNDERNEATH the clouds.
The only FE explanation I heard about this so far, is that it's just refraction, however, there are no further explanations about how or why it occurs in different weather conditions. Even if it were refraction, how does the sunlight shine under clouds when there is no water in sight. How does the sunlight viewed from ground level look consistent when different weather conditions are affecting the refraction in different areas?
Even if sunlight was just refracted back up to the clouds that doesn't explain why we see the sun literally appearing like it's under the clouds. If the sun just moves further away and the sun would look smaller then appear to go under the clouds due to perspective. However, around the 0:50 min mark the sun appears to at a huge size, too big to just appear to go under the clouds. Whether rising or setting, the sun always appears to come and go underneath the clouds.
This is easily explained in the heliocentric model but how does this on a flat earth?
