Because one is real, and the other is fake. Thank you for asking.
One of the parts of my visit that gave me chills knowing I was in The Place was when we got out on a boat in the middle of the Sea of Galilea (more like a lake where I come from LOL). I stood on that boat and did a 360 looking at the shore line in every direction, knowing I was looking at areas that Jesus did probably half of His ministry at. Some of the exact locations of lakefront villages mentioned in the New Testament aren't known today, except that they touched that lake somewhere within my field of vision. And Jesus was there doing His ministry at different beaches on that lake.
