Nice to meet you too! :D

By remnants, I'm referring to tools, machines... things that very obviously cannot be built by hand or through slavery. I mean, today we have massive cranes, tractors, giant trucks as big as buildings working out at mining sites, giant drills digging tunnels, and more. Inside of those giant tools are chipboards, motors, technology. I don't understand where all this stuff is now. That's not even bringing up the billions of cars we have. This stuff should be getting found in caves, fossilized in rocks, buried beneath the earth, etc. That's what I'm having trouble getting my head around.
