So...serious question ...please keep scrolling if you are easily offended [I Dont Like Small Talk]

I wonder how I am or anyone for that matter can trust or believe anything written in the bible when it was written by the hands of man ...humans hearts are wicked and lie by it's very nature . How can anyone trust it ? It's not as if God himself wrote these words. I am not asking this to ruffle any feathers ,I am just looking for insight .Just trying to make sense of things that make no sense to me.
