Have you ever received a piece of the moon for a gift? Very common, a certificate stating you have a square mile or something of the moon. So when you look up in the sky you can be assured that there is a little bit of you up there. HOWEVER .. NASA with its recent lunar building plans, has poo-poo'd all these certificates and "scams".
The moon is covered by the same laws as International waters, and therefore falls under the remit of United Nations.
What is that old phrase - not worth the paper it's written on
