I would expect to find fossil evidence of the animals spreading out from one location, either no animals except birds on Australia or some kind of evidence of how the animals got there in the last 4000 years or so. I certainly would expect that the current fossil record of man and animals would not have existed, nor would all that oil be in the ground if life wasn't millions of years old.
I would expect that the Bible would have been a bit clearer when it touched on science, not just saying the "circle" of the earth. It would have told of what the stars really are, it would have contained real medical instructions for longer life.
I would expect to find evidence that there really was an exodus outside of the Bible, evidence that David really ruled a mighty nation and not just a little village nation that never included the 10 tribes.
I would expect the Bible not to tell conflicting stories of the same events. (from Creation to the life of Jesus to slight variations on Paul's story)
I suppose the God of the Bible could have been okay with slavery, war, subjection of women to men, rape, etc. I wouldn't want to worship that God, but He wouldn't be much better than the gods of the nations. I guess they would have been copying the true god. I would have hoped that God was better than that. It seems that man made God in their image instead of the other way around.
