Why do people say spread? What I can understand is it's very hot on the outside and cools down the more the light goes thru the atmosphere.Problem is with oblique angles, in Britain why is Summers Night not colder that Winters Day?
Britains Summer night would be colder than Wintors Day
Axis Tilt does not work alone because then Britains Summer night would be colder than Wintors Day,
The current peoples view of light spread over a wider area for winter is seeming less likely.

Only in your view You can do an experiment with a solar panel. Hold it so it's front face is directly towards the sun, if you slowly rotate it so it finally has the edge pointing at the sun you will find the output decreases from a maximum when facing directly at right angles getting less as the angle is increased and the light hits at an oblique angle. No effect from atmospheric depth which is constant in this case. The important consideration is what effective area is pointing directly at the sun.
