When I was small, my father replied to my question about the birth of prince Siddhartha and said Buddhist literature exaggerate the things actually happened and more important things are the Buddhist vision and the teachings. Though we skip all the magic in the literature there are lot more things to consider and learn in Buddhism. I am glad this is what my teacher also said. According to Rahula Thero in the book, the most important thing is making peace inside yourself and whether we have a heaven or hell somewhere is not that important. I believe all the karma we are doing will follow with us and we have no escape. So do good!. A good book to read.
