We have the crude tools from the Romans which were around that time.
Where are the saws that cut the thousands of tonnes of Andesite in Peru?
I'll tell you what to look for:
They should be no more that 3mm thick, and at least 2 metres in length.
The Peruvian stone cut says so.
Otherwise, all that leaves is unknown technology.
In the known technology we know exactly what to look for. We all know what saws look like.
Simple logic really.
Im not claiming anything. You are the one claiming that ET were cutting stones on Earth back in the days.... Im saying that the credible evidence for that is still lacking. All you have are marks/cuts/holes that you cant see an explanation for.... Jumping from there to "therefor Alienzz" is beyond silly.
