One of the oldest rocks in existence, the Murchison Meteorite. It's 4,600,000,000 years old, and likely existed before the Earth itself had completely formed. Interestingly, it also contains amino acids, the chemical building blocks of DNA.

Wonder what is at the bottom of the ocean if this was found on land?

To be exact, amino acids are the building blocks of proteins, not DNA. Proteins are still crucial for life though. The “code” in DNA tells the cell which order amino acids go in when building proteins, but DNA itself isn’t made of amino acids. - a biologist (hopefully not being obnoxious by correcting you OP)
