Not only is there evidence of mechanical tooling, as is clearly demonstrated by the photos in the link that John provided, here, but there is also evidence from antiquity of laser tooling having been applied.

Here, in this segment of a Nissam Haramein lecture you can see what is the obvious result of laser-cut stone carvings, and an explanation as to why this evidence was omitted from scholarly discussions. (If you don't want to wade-through the build-up, the actual discussion starts about five minutes into the video. This particular video is just a ten minute segment of an eight hour lecture):

This evidence is just further proof that something much larger - than Humanity has been led to believe - was going on in antiquity.

I believe the evidence also indicates this same extra-terrestrial intervention continues to go-on behind the smoke-and-mirrors of reality in modern times....
