1) it is said that chinese are firmy deciding to send their astronauts to the moon in the 2020s.

2) what if a chinese pee on the moon? and leaving some amino acid, which is the most crucial element of all living forms.

3) after 500 million years, that chinese pee could be highly evolving, even into a humanoid species, on the moon.

4)although the interspace of the out space is a deadly enviroment to amino acid, let alone any other higher living forms, still human have found amino acid in the fallen stones from the outer space on the earth, which could be activised by a more advanced technology.

5) ok, maybe you will argue by saying, how can amino acid lead to human being? well, if not, at least , it will bring out some flowers and insects,or some simple living form ,such as one cell bacteria. but how can a planet full of flowers and insects without human eventually? how can god only creat flowers ?
