If we’re going to think about our headstones as a message to the future then I think confusion should be the goal. I’ve got a friend that’s an archeologist, I asked him once if they ever considered the idea that people left behind “evidence” just to confuse future historians, he said only when drinking and they all hope not.
LOL!!!
There's a large "temple / gathering place" (I dunno,it's hard to describe) in the mountains of Western Maine. It was built out of granite by a retired fellow; took him several years to do it. It's a fairly impressive site. Huge stone blocks set up, a large hand-hewn stone staircase, and so on.
I read an interview with him awhile back. In it, he said that it was a fun hobby and he enjoyed the view from the top. No religious significance, beyond the fact that it's so pretty and well-done that it's become a local popular spot for weddings.
Since I read the interview, I've wondered how many archeological sites that we ascribe so much significance to - think Stonehenge, Mayan ruins, etc - was more-or-less like this. Buncha guys puttering around on a few weekends, or the local lord had some serfs who weren't busy, and something was built that "looked cool" to impress the chicks.
