Well, if you watch fake TV shows about mysticism and aliens for a long time, you will find hundreds of similar proofs of literally anything. From the Yeti to the glass pyramids in the Bermuda Triangle. Self-proclaimed scientists in them build their narrative not on boring and incomprehensible scientific information to most, but on easy-to-understand, asociative fake facts or details taken out of context. All this is for the sake of popularity, selling worthless books and generally trying to make money on fools.
This story sounds very similar. What does a typical person know about jesus? He was immaculately conceived (therefore, his blood must have something wrong due to the absence of a father in the usual sense), everything about him was magical, including blood (an attempt to connect this blood with the blood of jesus due to unusual properties), as well as the fact that he lived and he died on the territory of present-day israel (just where little bottle was found).
Everything in this story looks as if it is designed from beginning to end for superstitious people who do not want to go into details, who believe in the word and do not expect anything serious from the field of science. Only in our case, it is rather not about ratings on television ( or internet) and increasing monetized popularity, but about trying to make people believe in the existence of christ, thereby becoming closer to accepting christianity. A typical trick of cheap christian apologists, who, by the way, also have a lot of TV shows filled with similar content.
