But neither science nor Islam has ever found a proof for a book similar to the Quran - claimed copies of the claimed "Mother of the Book" in Heaven - a god similar to Allah, or a religion similar to Islam, older than 610 AD when Muhammad started his new religion. This neither in history, nor in literature, nor in archeology, nor in architecture (f.x. decorations), nor in folklore, nor in fairy tales.
The fact that no trace is found in written history, which in what we call the Middle East, where the oldest parts of written history go back at least 3500 years, in China with its old history, among f.x. the Mayas (remember that Muhammad/the Quran/Islam claim Islam was all over the world), is extra revealing.
Draw your own conclutions.
"Muhammadans, not Muslims"
