So let's be clear I'm responding to your query.
I have done all the work I need to do on this topic. I have the images and the facts that I need to make my own informed decisions.
1) The stones are vitrified. Implying heat or molecular alteration. The sheen on the stones indicates this.
2) The stones have pock marks where something made an impression as though the stones were in a clay like state. Also they show smoothing marks similar to those made by a plasterers trowel.
3) From dismantled walls we see indications that upper stones sank into the lower stones. This indicates that the stones were soft at the time of assembly.
4) The small holes drilled into andesite show vitrification inside. Something burned into them. It was no copper pipe drill.
1. No proof of vitrification. Only shiny stones and one inconclusive test from one spot of a different stone type than the primaries.
2. Indentations which are assumed to be impressed because of their soft edges but could've been carved in any number of ways.
3. More of the same indentations which have been demonstrated as carvable by hand means.
4. More shiny rocks. Shiny rocks alone do not vitrification make.
And that as they say is that.
