Let's suppose the aliens already did this, but instead of a small disc, they wanted to send a message that no intelligent being could miss. Over a short span of 150,000 years, they redirected a bunch meteors into the moon in a pattern that encodes the last few digits of pi in a simplified resonant-fractal numbering system, which proves they know the angular momentum of the universe with fair precision. Clear and convincing evidence that would be visible throughout the solar system.

So yeah, I think no matter what we do to try to communicate with an alien intelligence, they would have to be very much like us (probably our own descendants or - who knows - ancestors) to even recognize the presence of the simplest message, much less decode it.

There is no last digit of pi.

Well of course not if your number system doesn't even exhibit fractal resonance in holistic projective encodings, given the angular momentum of the universe.
