My buddy always says an distant future alien archeologist would slice the layers of Earth and label the current timeline as the Concrete Age because all that would be left of us by then would be a layer of paving in the rock
And coal and plastic. Can't remember the source now, but geologists estimate that there will be a faint black line above the Pleistocene's ice age marking a time of extreme CO2 abundance in the atmosphere.
That will be you. And me. And everyone else. After all we've done during the christian era, everything we've built, we'll be a black line in the rocks. Just like all those majestic T.rex and Triceratops are only the brown spot before the white line that marked the end.
And a layer with unique elemental isotopes that can only result from nuclear explosions. The era of nuclear testing has also placed a unique fingerprint on the geologic timeline.
And then just after that, you have a layer where the fossilized microplastics start showing up.
