Was Mohammad Real?

"We can't be certain how the Arabs became Muslim", says researcher Tom Holland. Fascinating! Was Mohammad ("the Praised One") originally Jesus? Was Islam originally a non-trinitarian Christian sect that rejected the need for an atonement on the cross? The evidence from coins don't lie. People do. This is extremely interesting and new to me. Makes sense. The first video is by the Atheistic Republic, who got me thinking. The others back it up.
