☛ The oldest material of terrestrial origin that has been dated is a zircon mineral of 4.404 ±0.008 Ga enclosed in a metamorphosed sandstone conglomerate in the Jack Hills of the Narryer Gneiss Terrane of Western Australia.

☛ The oldest dated rocks formed on Earth, as an aggregate of minerals that have not been subsequently broken down by erosion or melted, are more than 4 billion years old, formed during the Hadean Eon of Earth's geological history.

☛ Meteorites that were formed in other solar systems can pre-date the Earth.

☛ The newly found zircon crystals in the Kendujhar district of Odisha are the oldest yet unearthed from Indian soil.
