The Oldest Crater from a Meteorite…Isn’t a Crater after All?

The video explores the history of impact craters on Earth and the Moon, focusing on the Maniitsoq structure in Greenland. Initially thought to be the oldest impact crater, new research using zircon crystals suggests it may result from tectonic and volcanic activity. The debate continues as scientists seek to understand the structure's origins and implications for Earth's history.
