I'm a Christian, and I think he sounds like a complete idiot with the crocoduck thing. I also agree that creationism/evolution has nothing to do with Christianity/Atheism. Proving either one will never prove the existance of God, or the lack thereof. I personally believe God made it all happen, but I don't know or care if He caused evolution or made man from dust. It doesn't matter.
I've heard long and heated debates about the rapture too. Christians believe that when it all hits the fan in the end days, God will pull all Christians up to Heaven with him. Some believe that happens at the beginning of the supposed 7 years of tribulation, some believe it's in the middle, some believe it's at the end. (pre-trib rapture, mid-trib rapture, and post-trib rapture) I've seen people kicked out of churches for believing a rapture time other than what the church preaches. I've also heard of heated debated about how many angels can fit on the head of a needle.
That's why I don't have a lot of Christian friends, and haven't gone to church in a while. I believe in God, and I believe the Bible is truth, but Christians tend to be vicious, relentless people who want to force people to agree with their beliefs. Of course die hard atheists preach and push just as much.
