Therefore who will you trust... The Word of God or Satan?
The bible is not a coherent book. It is a library of books of varied quality. It contains numerous errors and reflects the superstitions and scientific ignorance of its many authors.
It promotes an ethical position that would shame the most debased totalitarian regimes of recent decades. It endorses slavery, misogyny, kidnap, rape, genocide and infanticide.
One the biggest issues with the bible is that the extant documents contain more differences than there are verses. Many of the resulting contradictions are significant and cannot be reconciled without indulging in dishonest mental gymnastics.
It is impossible for an objective reader to conclude that it is of supernatural origin.
By the way Satan does not appear in the bible until after the Babylonian exile. He originates with the Zoroastrian religion of Persia. Pre-exile Jews had no problem attributing good and evil to Yahweh.
