What makes a stone a tool and not a rock broken in half?

Stone tools are often made of flint and have tiny workings on them that could only be man made, or specific shapes not caused naturally..such as an arrowhead.

The stone tools that are usually claimed to be as old as this, actually I will amend that to ALL stone tools as old as these, are NOT flint and do not have workings on them and are not in the shape of arrow heads, especially arrow heads since the bow wasn't invented until about 10,000 years ago, or spear heads. Usually they have an edge that could easily have been made by natural causes.

They will have a small edge running down a part of the tool and the scientists claim they are primative axes etc. All the ones I have seen that are supposed to be tools of this age are indistinquishable from ordianry rocks that have broken in some natural manner. IMO.

They also find objects next to the tools with scratches or marks that show the tools were used to work on them such as bones with scratch marks from having the meat scraped off.

So much of this field is nothing but guess work from a tiny number of facts. But the mystery of it all is what makes it fascinating.
