How could anyone actually believe the Adam and eve story?

For one, if they were the very first people on earth, they would have been here almost a million years ago. There are human bones that have been found that are that old. Even if it was like 200,000 years ago, it still would be unbelievable that the story of them actually carried on through the cavemen and stuff. And why would it be against anything to eat a freaking apple, they are good for you. I'm sure food was scarce. I don't think God cares what we eat when it comes to fruit
