We are told that "there was neither hammer nor axe nor any tool of iron heard in the house, while it was in building"
The go-to explanations tend to be fantastical things like use of the shamir, or the help of demons, or the stones levitate themselves.
But since the use of iron is specified because that metal is viewed as the instrument of war and death... Has anyone considered that bronze tools were used? Or even flint?
Bronze was likely still in common use, after all, and we hear of flint knives being used in the Tanakh. Plus, much of the temple was likely built of white limestone, which can seemingly be worked by bronze and flint (although there are disagreements on this) - https://www.archaeoresearch.co.uk/research/the-efficacy-of-flint-versus-bronze-chisels-in-ancient-egypt/
