According to New Scientist, strange rock carvings have been found in the North-East of England, resembling a heart-shape and a "footprint".
"We have absolutely no idea what they are," says Mazel, an archaeologist at the University of Newcastle. "They are nothing like anything we, or anybody else we have talked to, have seen before." He believes the carvings were not created recently - in the last 15 to 20 years - and could be as ancient as 3000 years old. |
