Please got to school and learn the basic principles. :-?

Heh heh ... Let's just agree to disagree.

I understand your argument, and you understand mine.

I'm saying the earth can be thought of correctly either as zero potential,
or, as an absolutely humongous conductor back to the power company.

Both explanations work just fine:
- For you, you prefer to think of the earth as absolute zero potential.
- For me, I prefer to think of the earth as the return path to the power supply.

Both are perfectly valid, so, my only objection is you telling me
that I don't understand.

I'd be perfectly happy to be wrong, but, I think I *do* understand your point
(and I agree with you); but I think you don't agree with me. So, we'll never
get anywhere under those circumstances.

So, let's just agree that I think you're right and I think I'm right,
and that you think you're right and that I'm wrong. That's OK.

BTW, a thought-provoking question would be:
Q: Where do you think the power company gets its electrons from anyway?
