"Binary code"?

No, that puts the nail in the coffin (along with the marvelous coincidence that aliens use 1AD as a reference for their dates, AND conveniently use the exact same positional notation (latitude and longitude) that we use, even using the Prime meridian as their starting point.

And they write in English.

AND they know the English spelling of these place names.

AND they use ASCII binary characters -- and only the ones that exist in the Roman alphabet.

Nopety nope.
