Look at the sun during sunrise / sunset, through clouds or reflecting off water and you will see Hotspots which are only possible from a close light source.
This photograph taken at sunset shows a Hotspot following the sun which is separate from the daylight in the sky
Using the day and night map you can see that the hotspot is not the same as the daylight
Compare observations with the way we are taught the sun illuminates the sky and how sunrises / sunsets occur and it seems almost comical
