Remember that oil spill in the Gulf of Mexico? The alarmists screeched that it was the end of the world, that a good hurricane or water spout would dump the oil on Mississippi? Then the ocean dissolved the oil, and all was well.
And there's Marcahuasi. Are those things statues? I don't know. They might be.
No telling what relics and artifacts that once existed but are no longer recognizable.
Devouring Time, blunt thou the lion's paws,
And make the earth devour her own sweet brood;
Pluck the keen teeth from the fierce tiger's jaws,
And burn the long-liv'd Phoenix in her blood;
Make glad and sorry seasons as thou fleets,
And do whate'er thou wilt, swift-footed Time,
To the wide world and all her fading sweets
Such a great quote in the context!
There are similar (to Marcahuasi) things in Romania which were used by the Neanderthals
