Tena,
Sure we had world wars and what not, it's not a good reason to feel the bible is true, in fact we probably don't even understand Jesus was talking about being that these things were written many decades after the supposed dialogue took place with nobody writing it down as he spoke , so expect much of it made up to sound good, you know how word of mouth gets corrupted very quickly the more people in the link to pass it on to it's final destination which is somebody's ink and pen writing the holy script.
