Electrons do not return via the earth path. To be pedantic, the

They travel a small fraction of a millimetre back and forth along the
wire. Which is pretty exciting by electron standards.

For alternating current?

Yes. For DC there is a constant drift velocity, but again it's very
slow; fractions of a mm per second (though it varies with current and
conductor properties).
