Idk why you're getting downvoted it is fun (or scary) to think about. I think we are wayy too confident in our assumptions of humanities history. The reality is our known history could only be a tiny sliver of what humans have accomplished with the rest lost to time. It could also be mostly wrong lol. What if the reason we mostly find stone age artifacts is because stone is the only thing that lasts that long?

For example if our global civilization collapsed tomorrow how much would really be left in 10,000, 100,000, a million years? There almost certainly wouldn't be any trace of our highly advanced computational capabilities (arguably our greatest achievement).
