Is there a geologist in the room? How old is Earth? And are we now capable of identifying anything that is 1.5 billion years old? Maybe an old chevy...

The oldest object on Earth is a grain of zircon that's nearly 4.4 billion years old. It's the only thing we have from deep in the earliest Archean, and it provides evidence that even at that time, Earth had liquid water on it
