Wrong. You are ASSUMING that the sun is so hot it would burn everything. Obviously it does not, as photos from planes above clouds show the "hot spot" on clouds. There would not be a brighter spot on the clouds if it was far away.
Also, sun rays are shaped like a wheel through clouds.......... If the sun was really thousands of miles away, the rays would all be straight......... CHECKMATE
Not how it works, genius. The sun is too far away as it moves away from you, taking the light with it (which is also why it gets smaller as it sets, that gives it away as well). Grow a Brian.................sheee
