the Great Pyramid of Giza
The Great Pyramid was finished around 2560 BC and remained the tallest structure on Earth for about 3,800 years, until Lincoln Cathedral's spire in 1311. The comparison worth holding on to is Cleopatra: she was born in 69 BC, roughly 2,500 years after the pyramid was built, and lived roughly 2,000 years before us. The pyramid was more ancient to Cleopatra than Cleopatra is to anyone reading this.
sharks
Scales from shark-like fish appear around 450 million years ago and unambiguous shark teeth by about 420 million years ago. The first trees appeared roughly 385 million years ago, so sharks predate trees by tens of millions of years. They also predate Saturn's rings on most current estimates, and they have survived all five mass extinctions.
Deep-time dates are approximate to within tens of millions of years and shift as new fossils are found.
