Kirk Cameron

British physicist Stephen Hawking may be one of the smartest humans of all time, but his recent claim that Heaven doesn't exist were guaranteed to generate significant backlash. Enter actor and Evangelical Christian Kirk Cameron.

Hugely active in his church, Kirk says Hawking, who called heaven a "fairy story for people afraid of the dark," has no scientific evidence to back that up.

How can the Growing Pains star say that's the case?

Well, Cameron told TMZ the following: "Professor Hawking is heralded as 'the genius of Britain,' yet he believes in the scientific impossibility that nothing created everything and that life sprang from non-life."

"Why should anyone believe Mr. Hawking's writings if he cannot provide evidence for his unscientific belief that out of nothing, everything came? [Hawking] says he knows there is no Heaven. John Lennon wasn't sure."

"[Lennon] said to pretend there's no Heaven. That's easy if you try. Then he said he hoped that someday we would join him. Such wishful thinking reveals John and Stephen's religious beliefs, not good science."

There you have it. Kirk Cameron vs. John Lennon and Stephen Hawking, all in one story. Bet you didn't expect that in your daily dose of celebrity gossip!

What do you think, though? Is Heaven legit?

Kirk Cameron is best known for starring in the 1980s hit Growing Palins. Nowadays, he is an active Christian evangelist. This brought him to UCLA recently.

He went to convince college students that Darwin's theory of evolution is dead wrong, and while he can believe what he wants, Kirk's debating needs work.

Several UCLA students asked Cameron about Darwin, at which point Kirk stated that "I believe that Darwin was absolutely ... that the end game was to make God ... was to remove God from the world view of .. I think that that was the end game."

Hard to argue with that Sarah Palin-esque doctrine.

Kirk Cameron on Campus

Kirk tried to link Darwinism to religion (and a bad one), saying it's "extremely based on faith." A student's reply? "Not really, it's based on a lot of evidence."

Cameron was on campus handing out copies of a "revised" edition of On The Origin of the Species, in which the author attempts to connect Darwin to Hitler.

Maybe next time Mike Seaver will take part in a little debate prep boot camp before getting straight up learned by 20-year-olds with cameraphones.
