TIL that we don’t know who named the Earth. Unlike other planets there are no records of how it got its name. The name Earth, and variations of it, date back 1000+ years. (www.skyatnightmagazine.com)

What's wrong with dirt?

On a planetary scale, all soil is dirt, because it's all been displaced so many times from glaciers and mountains and oceans and taking part in the biosphere, you can't tell where each particle was originally weathered from or which plant first captured it from the air. No one can trace sod to a fault line.

It's hard to have a rich history when evwn sharks are older. I bet you can't even tell if a soil is from regolith younger or older than Pangaea!
