Since the second half of the bible was written in Greek, many words have meanings that can't be translated into English in any exacting way, just like Hebrew can't be translated into English either. It's even harder. The Torah was taken and translated into Greek, then translated into Latin, then books were taken out, changed, then translated to English. How it can be taken for its word is beyond me. The Hebrew language, a little like Greek, is not at all like English. Every character has many meanings. This is why there is the Talmud and a continuing argument among rabbis about what the hell it all meant, because it can be deciphered in a ton of different ways, even numerically. So then someone (a human person or people) took this hard-to-decipher scripture and somehow translated their interpretation of it into Greek, and from there it evolved and changed. How do we know that interpretation, in that moment in time, was appropriate or "correct?" Maybe there isn't one way to view this text. Different people wrote the books of the Torah, that we know. But that's really about all we know. We know that each Torah is copied character by character exactly as it's been written for thousands of years and checked over by rabbis to make sure there are no changes made before it can "be" on the scrolls. But who knows if there was some point in time when someone was in power to make changes before this tradition, just as the Catholics made changes when they were in power, or the emperor of Constantinople or whatever history we don't know about...
Also, the New Testament wasn't even written until at least a few generations after the Jesus thing occurred, if it even did. There are no other records of him existing anywhere else during those times. There are no physical relics left behind to prove he was here other than the scripture--not to say that is NOT something, it is. But I'm talking about some kind of remnants of a building, structure, engraving during that time, an old sandal? Some physical evidence documented that he was around before the 200 years it was documented that he was here.
