The Sun stays the same size — and sets bottom-first

The claim

“The Sun is a local spotlight that recedes to a vanishing point at sunset.”

What is measured

The Sun holds a steady ~0.5° (about 32 arcminutes ) across the whole day; a nearby “local Sun” would visibly shrink toward sunset. It doesn’t.

What would show this is wrong

the Sun’s angular diameter shrinking measurably between noon and sunset.
