The great reptiles were the most successful life forms ever to populate this world. For 140 million years they ruled the Earth, filled the sky, swarmed in the seas. At this time the mammals, the ancestors of mankind, were only tiny, shrew-like animals that were preyed upon by the larger, faster, more intelligent saurians.

Then, 65 million years ago, this all changed. A meteor six miles in diameter struck the Earth and caused disastrous atmospheric upheavals. Within a brief span of time over seventy-five percent of all the species then existent were wiped out. The age of the dinosaurs was over; the evolution of the mammals that they had suppressed for 100 million years began.

But what if that meteor had not fallen?

What would our world be like today?

I have read the pages that follow here and I honestly believe them to be a true history of our world.

Not that belief was easy to come by. It might be said that my view of the world was a very restricted one. I was born in a small encampment made up of three families. During the warm seasons we stayed on the shore of a great lake rich with fish. My first memories are of that lake, looking across its still water at the high mountains beyond, seeing their peaks grow white with the first snows of winter. When the snow whitened our tents, and the grass around as well, that would be the time when the hunters went to the mountains. I was in a hurry to grow up, eager to hunt the deer, and the greatdeer, at their side.
