I expect better of atheists. The video is no more than a rehash of the claptrap that was both presented and debunked in the 1800s. The majority of scholars say that Jesus did exist, and even point out that the Gospels themselves are a credible source that Jesus did teach. It can also be shown that Christianity has its roots in Judaism, not in Greek, Roman, or Scandinavian stories.
That being said, no culture lives in a vacuum, and each generation has its own perspective of historical figures, religion, and wars. This is why it is wise to get back to the closest accounts of what was written about any historical figure, while keeping in mind the effects that person had on society.
Does this prove everyone should become Christian? No. People still have to develop and have faith that Jesus and the Apostles were credible witnesses, were who they claimed to be, and were sent/anointed by God with a message.
Atheists, if you don't believe, you don't believe. We accept that. However, you lose every ounce of credibility when you say you don't believe because instead you believe nonsense that was debunked more than a century ago, while scholarly studies do show that Christ lived. Where faith comes in is whether one believes he was just a man, or whether one believes he is the son of God.
