I would disagree that traces of human activity would be hard to find. We dig like no other species has dug before, leaving out mark not just on the rocks of our own epoch but on those have preceded it.

On the other hand I find it hard to argue that our activities so far would be classed as anything other than an event rather than an epoch.
