Easy.
Contrast the life of Jesus with the life of Mohammed.
Mohammed was a pirate, a warrior, a pedophile, a polygamist, a rapist, a mass murderer, an executioner, a torturer, a thief, a liar, a truce-breaker, a kidnapper, a slave trader, a racist, a Jew-hater, an unspeakably cruel tyrant, and a genocidal savage.
He boasted of personally beheading between 600 and 900 Jews in one day.
The Koran promotes Mohammed as “Allah’s” prophet.

If you’re truly interested, Lee Strobel’s “Case for Christ” details the reasons for this measurement of verifiability of His life.
If you’re a “mocker”, pound sand.
