 Signs of Life Signs of life were located in an unusual rock formation in what is now a desolate part of the Arctic. The site, on Akilia Island in West Greenland, is known to be 3.85 billion years old - the oldest known collection of rocks on Earth! The Earth is thought to be about 4.6 billion years old, and this ground-breaking discovery pushed the age of the oldest known life on the planet back almost 400 million years from what was previously known. But don't get too excited. The form of life discovered there was likely just a simple micro-organism, although its actual shape or nature can't be determined. Over time (a whole LOT of time), heat and pressure have destroyed its original structure - which was likely just a "blob" even then.
