I'll take that. Obviously he hasn't proven it to most people in the world.
The "convincing" is pretty thorough, through evidence of population growth rates, growth of the Sahara desert, lack of a larger Mississippi delta, fossil data that's been left out of the evolutionist textbooks that are prevalent in schools at all levels, fossil, archaeological, and anthropological evidence that shows geological timelines to be severely misconstrued, dinosaur soft tissue that somehow has not decayed after all those millions of years, ice age evidence in the glacial record, evidence through the results of the Mount St. Helens Eruption, the formation of canyons, including the Grand Canyon, and much more. He also described all the "missing links" that have been put forth and hypothesized. I don't want this to become a discussion of the issue, however; I just want to encourage people, whether Christian, Agnostic, Atheist, or just people with questions, to go see this guy if you get the chance. He's definitely well-versed and unafraid of hard questions or even accusations and challenges.
