Is there proof outside of the bible that jesus existed?

From the video description:

"This video is part of a live Q&A with author and former devout Muslim Nabeel Qureshi on March 22, 2015 at Christ Community Chapel."

In this short 3 minute video, Nabeel Qureshi points us to answers regarding evidence for Jesus' existence outside of the Bible. The short answer to the question if there's proof outside of the Bible that Jesus existed? -- Yes! Of course, he can't go over everything there is in only three minutes, but consider this a primer as he directs you to other works to check out and perhaps research.
