What would you do if it turned out that satan influenced to whole Bible?

that they was the words of the devil to create division amongst the population.As God is the father what if he gave man freewill and nothing else,then left us to live our life with the information that is contained within our DNA (like as adults we know the difference between good and bad)if he made us in his image and stated that "man has become like us"(God).With this abstract idea is it possible for the beast to have done this? How can you tell? real answer please stretch you minds
