Do you think that "the earth" must be giant?

Idiot, meaningless babble.

Your mobile phone has earth connection, radio on satellites and planes
have earth connection because they are on the chassis. Accept this and
move on.

Some antenna systems do have an earth connection, many don't.

All must have.

No, that has never been true and you have been told so many times now.

You are a babbling idiot.

All must have for protection against the build up of static.

No, that is not always true either.
