PLEASE HELP! This was a book written somewhere between the mid-70s and mid-80s. It begins with an expedition to the moon where they discover a body in a spacesuit that is 10,000 years old. The final premis of the story is that this race of beings lived on a planet that was thrown out of its orbit and eventually collided with Earth, and they were the original inhabitants of this planet.

Ooops. Ralphr7, you posted in the wrong sub-forum. Should've posted here:

Book Search - Science Fiction Fantasy Chronicles: forums

I am sure one of the mods will be along shortly to move this thread to where is belongs.

The above being said, I don't have an answer to your query. Sounds familiar though (wasn't there a movie with this theme, starring Gary Senise??).

This is the 'Giants' series by James P. Hogan. The first book is called "Inherit the Stars" and is about the discovery of the antiquated corpse on Luna.
