Perhaps it is real - I am one who doesn't care unless it is proven as being a direct and physical connect with my Savior. Until then it is as you say, "very interesting".
I just can't get worked up about "things" as a way to connect with Jesus. What I can't see and what I can see, but cannot grasp, is enough to tell me how awesome my God is. When I think of Him as "I Am!", I understand that before He spoke us and the universe into being, He was. As long as the universe and time as we know it exists, He is. After the universe is gone, He will continue to be, even though we have no way to grasp what it must be like to exist outside of time and space. I can sense the ramifications of my God's existence and being at some primitive and visceral level, but cannot even begin to comprehend the Truth on an intellectual level. "Stuff" only serves as a diversion.
So either you didn't read the article at all, or completely ignored the physical evidence which includes blood at the locations in which Christ was lashed, nailed to the cross and stabbed with a spear.
I agree with your statement on not needing physical evidence as a matter of faith, however I still found this a fascinating read and it may not increase my faith per se, but it does bolster the authenticity of the Bible.
I look at this from the perspective of "once again, science proves the existence of God" ... or in this case, his Son. I think it's interesting that more and more, science does confirm our Father.
