The video at minute 3:28 says "The historical accounts found in the Bible depict Jesus (whose Hebrew name was Yahusha) as a factual, real person." --- this is misleading. The gospel writers do not call themselves Historians, nor do they write to people who are not already Christians. The video narrator is doing a little bit of slight of hand here by attempting to present the gospels as 'Historical accounts' and that the facts therein can be used to verify their validity. First, verifying facts against historical facts does not verify the validity of the gospels -- at all. It doesn't matter whether they are historically accurate. That cannot verify whether they are valid. Secondly these are not textbooks for students. They are written to people who are already Christians, already heavily knowledgeable about Judaism, and they are religious not historical texts.
Suppose you are an Anne of Green Gables fan. You are very big into Anne of Green Gables, and you write a story about Anne. Then the world is destroyed so that someone finds your Anne book two thousand years later not in the Fiction section of a bookstore but hidden in a basement under some ancient newspapers. Lets say few books survive, and nobody remembers the strict categories 'Historical', 'Biography' or 'Fiction'. Now how are they to know whether the book is a real story or historically accurate fiction? Well, the videographer above would presume that Anne of Green Gables must have been an actual real person, putting the book to a perverse use. Anne of Green Gables is fiction, but you are supposed to know that before you read it. Similarly you have to know ahead of time whether the gospels depict a man or not. They cannot be used to 'Verify' Jesus existence, nor should they. That is a misleading use of the gospels.
I want to add that the videographer claims at minute 11:30 that Jesus "Fulfilled 350 prophecies that were written about the messiah of the Old Testament." This is an ignorant person making zealous videos. Their intended audience is not scholarly, yet they want to tout scholarship. I have pointed this out before in other thread, but any layperson can debunk this claim. Start in Matthew, the first gospel. Everywhere that Matthew says something is fulfilled -- use a concordance and try to find out what Matthew means. Look up the relevant passage. What happens is not prediction-fulfillment. Matthew refers to imitation. Jesus imitated the actions of the prophets, and all through Matthew this is denoted using the term 'Fulfill'. What this videographer does is terribly confusing, and no Jesus does not perform 350 actions predicted by prophets. That is terribly dishonest.
