Columns? Streets? I live in a house that is over 100 years old, and had not been occupied since the 1930’s. I promise you, I have been from one end of the adjacent property to the other with a metal detector and haven’t found the first coin, tool, or man-made metal object. But, I promise you, “microbes” didn’t build that house.
Sometimes i wonder if they make up thid sorta thing to hide our own history from us.....
What are the layouts of the stones? Were the microbes city planners too.... i smell they found one or two microbe structures and wrote it all off.
I live an almost 300 year old blacksmith’s log house.
After the first day of digging up a bazillion rusty nails, horse shoes and bits of chain, I gave up metal detecting.
:D
