Worse, a billion year orbit would circle the galaxy a few times. You would
have to predict where our sun would be and I think stellar motions in the
galaxy are too chaotic.

Imagine Europeans from the year 1493 trying to send a message to us by
'carving' it in the earth of the new world. In a billion years the moon
will have experienced over a thousand separate waves of colonization.
And many more wars.
