Jesus was not crucified = fake
Any wonder liberals and Muslims are allied? There is no objective truth in those religions. In one of those religion, “truth” was dictated by God to Muhammed, and not subject to scientific test. In the other, “truth” continually evolves as the shared belief of the elite.
When Shak said the earth is flat is was a joke. When God said it was flat in the Koran, that settled it. The earth only appears to be a globe. It is merely useful for certain purposes to suppose it is round. We make calculations based on the false assumption that the earth is a sphere revolving around the Sun, even though we know from the literally forever true Koran that the earth is flat.

Therefore when the Koran has fake history about Jesus or about Moses or Abraham, etc., that are not validated by contemporaneous writings that have survived to the present, or by long lost tablets and other writings recently discovered, or by scientific discoveries made long after the Koran was published, we go by the Koran because to do otherwise undermines the claims made by Islam concerning the Koran and undermines Islam itself.
Also, because otherwise is blasphemy and subject to death.
