You’re welcome to your opinion, no matter how far off the evidence it is.
The many thousands of dolmens found around the world are anything but natural formations. The many walls constructed from large, rectilinear stones are far from “natural” (examples:

Thank you for the links.
The first one could be construed as non-natural, but the second one is definitely natural.
Even if the second one is man-made it does not signify any great leap from the creators of stonehenge i.e. neolithic hunter-gatherers.
This isn’t even the pyramid level (Chalcolithic) - that’s not to dismiss stonehenge as nothing, they are impressive, but they aren’t “civilizations” as in the sense of “civis” i.e. cities.
