The stone walls in New England are not ancient, they're from early settlers who cut down the forests and created pastures and farmland. The soil in New England is very rocky, so tilling it produced lots of rocks. The rocks were used to create walls to demarcate property lines. Now that the forests have regrown, there are many forgotten/disused stone walls deep in the woods, but they were originally put there by farmers.

Edit: I'd add that these stone walls are still used by surveyors, especially when the historical records may be spotty, but also just because they in many cases happen to still fall along existing property lines. There _are_ a few "ancient" stone sites in New England of disputed origin, including "Mystery Hill" (also known as "America's Stonehenge"). But there is a strong argument to be made that these were constructed by modern Americans as hoaxes.

Most of the literature attributes the walls to early settlers and colonists. The vast amount of walls especially in places that were never settled makes this hypothesis wrong and outright misleading. Some walls were created by colonists but you would need millions and millions to make _all_ the walls in this region with in a time span of 150-300 years.

It's simply impossible for the farmers to have built all the walls, even if thats all they did was build walls all day every day for generations.

The early colonists were sustenance farmers and there are no journals or diaries or documents which talk about them building walls.

I don't write that much about making excel spreadsheets. I'd assume that when they stumbled over a rock they put it on the side of their field, arranging it to a wall. They might have just wrote down "field work" in diaries (if they had the time to write).

You don't write about spreadsheets, but if we look at the library or the internet we can see that at least one person writes about spreadsheets.

There is not one piece of written evidence that the colonists created all the walls. There is not one piece of written evidence that the native Americans built the walls.

We don't know who built the walls.
