A valid point if the geological record’s timeline is accurate.
For the sake of curiosity, query duckduckgo with:
ancient megaliths saw marks?

There are multiple sites worldwide that seem to show saw cuts in stone which predate our use of diamond-tipped saws.
Do you think there is an innocent explanation for those? If so, what would it be?

It has been established by experiment that even hard stone such as granite can be cut with very simple technology, for example, one experiment used a simple water wheel powering rope cordage(!) for the sawblade to cut hard stone, and water to lubricate the saw. Obviously the rope wouldn’t hold up for very long but rope is easily replaced and the experiment did establish the viability of the method to make straight and deep cuts in stone with a low level of technology.
What difference would the geological record’s timeline have to do with the fact that no metallurgy is found prior to the ice age?
Those aren’t sawcuts. They look like the quartzilite string cuts we know they used
There is not any stone that requires diamond blades or even carbide to cut. We have them and use them because they cut faster; and, we are an impatient lot.
