There are many who claim that the Bible/Torah is a fabrication of various stories but if that was true then how could it be the greatest predicator of some basic truths that we hold today. Here are just two that stand out in my mind.
(1) G-D tells Abraham that his offspring will be descendants of many powerful nations. Today Christians, Jews and Muslims all accept that their faiths start with the Abraham. What makes this so significant is that in between that time their could have been a Sam, Larry, or Lisa who said they spoke to the Divine One and created a different major faith but this has never occurred.
(2) The bible tells us that the Jews will be dispersed around the world and then return back to their holy land Israel. History shows this occurring to the T. The Jews could have been dispersed after being conquered to one or two countries but instead we can see that after the 2nd Temple was destroyed they we moved to lands around the world.
I would showcase more biblical truths by truthfully I have to go to work shortly
