iirc the seasons are caused by the wobble in earth’s tilt. In summer your hemisphere of the earth is tilted “forward” so that it’s directly facing toward the sun, and in winter that hemisphere is tilted away to point not directly at the sun.
That’s why when one hemisphere has summer, the opposite hemisphere has winter. If seasons were caused by a change in the earth’s orbit distance then the entire planet would experience the same season at the same time
wobble or not is a matter of reference frame.
In an Inertial frame you are of course right, but
in relation to the suns surface I’d argue the earth could be said to wobble.

That’s not really the “wobble in Earth’s tilt”, that’s just the tilt itself. You have a much better understanding than Calvin’s dad though.

Yup you’re right, as you said, i was close but not quite right

And actually on the Northern hemisphere we are farther from the sun during summer than winter.
