I watched the first 1/4 of the video, and it seems like they corner and bash Christianity. Saying creationism is a lie and it is geared towards distorting reality, creating bloodshed and rupturing the unity of humankind....... To be honest, I can think of over a million ways to dispute this. For those who think that Christianity is disproven by science should look into Dr. Kent Hovind, who is also very skilled at persuasion (be careful there are many people online that publish things against him, but too afraid to debate him in person or on the phone).
The video has been carefully engineered to unfairly convince the unsuspecting public. There are also very similar videos that claim the holocaust never happened (offering seemingly-irrefutable evidence), there are also ones claiming that Pearl Harbor is a setup, the government conspires to hide aliens from the people, that President Bush is a robot....etc..
"You shouldn't believe everything you watch on TV."..especially on youtube... The bottom line is that these people are good at persuasion. They attempt to use objective science to lead us away from reason and into belief, yet they claim to attempt the opposite. In particular I love how they present a widely-accepted solid fact, and draw a somewhat disjoint and radical conclusion leading the audience to believe that since their fact is true then their claims must be true as well.
You should ask yourself basic questions:
What if the Iraq/afganistan war didn't happen (need political and economic knowledge to answer this)? What if there were no taxes? What if the world did not have religion? What would happen if we could not distinguish between right and wrong? Why do we have the capability to ask these questions? - they do not increase our fitness and/or reproductive success

My point is that there are countless phenomena that simply cannot be explained by science. Regarding the guy who makes fun of God by incorrectly widening the reasoning scope, I can also make fun of evolution by widening the scope: "We all came from a soup, which came from a rock." -- sounds pretty stupid too eh?
You need to look at both sides of the argument in order to realize how much BS and a waste of time the whole thing is, and how good they are at persuasion. As I said, there are hundreds of videos like that trying to "prove" different points.
