Welcome to Litsy!

This is hard science fiction and not much happens in the way of action - most of the book consists of scientists talking amongst themselves as they gradually unravel the mystery of a humanoid found on the moon 50,000 years after he died. I liked it up until the last chapter and epilogue which had me plumbing the depths of my brain to recall what I knew about the human evolution timeline and the history of the moon. I just couldn‘t buy the ending.

Published in 1977. Optimistic view of the future I don‘t see happening any time soon. Some of the computer technology portrayed in the book is similar to what we have though.

This book is an awesome read. They find a dead astronaut on the moon, well the investigation begins and they come to find out he has been there for thousands of years. How did we get on the moon when those ancestors were still in caves? Book one of a trilogy you will love all three.
