Out of Place Artifacts is a fascinating subject. There are too many of these unusual objects for them to be fakes. I've already written several books on this subject including "Strange Objects Which Should Not Exist", "More Out of Place Objects", and "A 300 Million Year Old Civilization Existed on Earth".
This is version two of this book and I've compiled everything I could find out about these unusual finds from my prior three books and additional research. 57 artifacts are covered in detail.
I've included all of this information except that specifically related to Aliens and UFOs since that information is in my books on those topics.
The information here is presented in five parts:
Part A: Artifacts Found in Historical Times
Part B: Very Ancient Objects to Millions of Years Old
Part C: A Civilization 300 Million Years Ago
Part D: Human Footprints in Rock
Part E: Artifacts of Undetermined Ages
I hope you find all of this information as interesting as I do since it changes our understanding of the history of our planet in incredible ways.
