The oldest known individual living thing on Earth is a tree older than the pyramids

A Great Basin bristlecone pine in California's White Mountains, nicknamed "Methuselah," has been growing for roughly 4,850 years, confirmed by counting its growth rings. Its exact location is kept secret to protect it from vandalism. Unlike clonal organisms that spread via shared roots, it's a single continuously living tree that predates the Egyptian pyramids.
