On the simplified drawing the electron flow from antena to ground.
Are you sure that the diode may be mounted in the opposite direction?

My only question is why does my crystal radio work without a ground
connection? Yes the radio does work better with a ground but that does
not negate the fact it works without a ground.

Most receivers has a chassis as a ground.

And yes the radio works
with the ground and antenna connections reversed. The diode is a piece
of galena.

Does "it works exactly the same"?
S*

yes

I haven't read all the thread.

I always see the diode in series between the antenna and the headphones.

You will get a much louder audio signal if you connect a germanium diode
( 1N34 ) in parallel with the phones.
