Sharks are older than trees.
They're older than a lot of things. Land plants, Yellowstone, appendages,dinosaurs, doritos.
The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago.
There's no shark without Mountain Mama
What do you think the first several hundreds of millions of years were like before they had Doritos?
I just checked, Polaris is about ten times younger than sharks. The other two stars of its ternary star system are older, but not visible to the naked eye, so early sharks would not have been able to use them for purposes of navigation.
Much of Earth's water is older than the Sun so the shark's likely swam from space is my best guess.
I mean the protons and neutrons are never new, all of this stuff is just second hand, cobbled together recycled garbage!
