There was a man named Muhammad.
In his day the Middle Eastern tribes worshipped 360 different gods, with Allah, the moon-god, chief among them.
His family worshipped this moon-god, so he created his religion around it.
The symbol for the moon-god was a crescent moon, thus he took this as the symbol for his new religion.
He decided that this moon-god would be the only god, forcing all tribes to worship it alone.
He was a man of violence who beheaded all who refused to convert or extorted them for protection money.
Mecca was built as a shrine to this moon-god.
And now millions of dear muslims have turned away from this moon-god for love of Jesus, the God who is love. Though they are killed or beaten or lose all that they own, they now know a love that is stronger and no fear of a moon-god can hold them.
