Spoiler alert! If you haven't read the book yet, I suggest that you do not read below and return when you have.

The extinction event of the dinosaurs, 66 million years ago, is readily accepted. However, our planet has supported life for at least 4.3 billion years. Therefore, it’s not unreasonable to speculate that, not only the dinosaurs, but all kinds of life forms have come and gone in the annuls of time.  I propose that one or several of these life forms may indeed be human. Beings exactly the same as us:

intelligent, creative and self-aware, that have somehow faced extinction. Clearly, a certain amount of happenstance is required for humans to fully develop. If this was lacking, in any way, a convenient solution would be to enhance our genome with a previous version. Enter Caban and Keeva, better known as Adam and Eve to do this dauntless task..
