Um, Um, Is There Evidence of Tool Marks?

There's no real rhyme or reason for why these indentation, these, as you call them, step-alike features, maybe where they are. And these steps are sometimes like several feet hot at all. Um, then there's the other claim that, that Kimura made that there's evidence of tool marks. He doesn't show any pictures of these tool marks. His paper just has, just says that he saw scars from tools driven in as a wedge that have been found among other markings in the structure.
