Disappointed archaeologists
If an archaeologist had found this while walking, he would have been delusional for a couple of seconds because it looks like an ancient object found in the middle of an excavation, but it isn’t. And it is not a statue from Easter Island either.
This is an ordinary boring plastic gallon found somewhere in the world. And this is an excellent time to remember not to throw polluting objects on the ground. Let’s take care of our planet; it is the only home we have.
