Mohammed was indeed a prophet, but we now know that he was in fact one of many human messengers from another planet ruled by advanced extraterrestrials. Jesus was one too, as were many other prophets throughout history. The aliens have recently come to a man called Rael to explain the actual truth of what happened. Details:

every life form on Earth was created by advanced human scientists from another planet with 25,000 years of scientific advances who, according to Raelians were originally called Elohim or "those who came from the sky", and that some forty prophets in Earth's history were sent by Elohim whose messages were misunderstood and distorted by humans, largely because of the difference in the level of scientific understanding between the advanced race and our primitive one.
