For the sincerely open minded seeker of truth with an inquiring mind about the facts surrounding the life of Christ this is very helpful. For very skeptical and scientific minded people (with a non closed mind being a prerequisite) the book "What's So Great About Christianity" by Dinesh DSouza is very helpful for following all the great religions, great and not so great philosophies, government systems, necessity and origins of ethics etc out in a very linear way to see what you get. After reviewing the evidence, it takes more faith to believe than not believe.
And for the person named MB with a philosophy degree below (who must have fallen asleep through the movie or have an extremely narrow mind which light cannot enter) and commented that there is "no tangible evidence that Christ existed-whatsoever" why are we writing every day the date on our calendars which is currently 2022 AD (Anno Domini) which is translated to In the year of our Lord -Jesus Christ. If He never existed we would certainly be writing some other year date as a reference point. There's more documentation of Jesus Christ than Julius Cesar, yet no one questions that Julius Cesar existed.
