And I hope I did make it clear to all: all you need to make a rock shiny is have microbes and lichen grow on it.
But to increase the speed of that process you need some plant/herb with a sh1tload of oxalates in its leaves.
Maybe all I posted is nonsense, true, but at least I backed it up with accounts from people traveling through the Amazon.
And that's Hiram Bingham and Percy Fawcett.
Ivan Sanderson claimed to know what plant it was, but he said he forgot its name. But it must be a well-known plant, and you can buy it in every florist shop according to him.
Then we have a Davidovits who used a brewage made from several plant juices, and was able to mold stone, just like the Huanka did.
Although I don't agree with him when he says that the ancient Egyptians used molded stones to build their pyramids, I still think that part of his theory can be applied to the way the Incas built their structures.
If 'only' the surface of their blocks was chemically altered (= softened), then we have a non-alien explanation of how it could have been done.
And I haven't seen anything from Zoser that comes even close to explaining why it must have been aliens. Well, aside from posting some statues.
"I don't know how it was done, we're not sure how to do it right now, so it must be aliens."
The answer to your question is that analysis reveals heat. Read the report in 4401.
The conclusions and implications are obvious.
No running away from this one Abe.
If you can prove the conclusions of the report wrong then you have a case.
