Nah. There’s NO way its because you’re closer to the sun. Thinking about the scale you might be .0000000001% closer to the sun, of its total distance. But the atmosphere being thinner, I’d imagine you’re getting more sunlight/less sunlight reflected by the atmosphere. Likewise, I don’t know how much the atmosphere reflects of all the sunlight passing the earth.

It’s a cool question.

I think the guy meant to say irradiance and not irradiation. The distance from the sun has basically no effect on the irradiance. The shorter distance the light travels in the atmosphere would probably have some small effect though.
