The symbol of a crescent moon and star has been used since antiquity. The Greeks used it to represent the goddess Diana, the Carthaginians used it to represent their goddess Tanit, and it was used in worship in Central Asia and Siberia. The symbol has been used by cities and to commemorate battles. It has been imprinted on coins, flown on flags, and approximately one thousand years ago, it was painted on the ceiling of a rock canyon in the American southwest. Some of these artifacts may also record the supernova that created one of the jewels of the night sky, the Crab Nebula.

The crescent moon and star is an internationally-recognized symbol of Islam. The symbol is featured on the flags of several Muslim countries, and is even part of the official emblem for the International Federation of Red Cross and Red Crescent Societies. The Christians have the cross, the Jews have the star of David, and the Muslims have the crescent moon, right?
