Re: Pre-human civilizations on Earth
On the other hand, the Elder Things were colonists, as were their enemies. For a game setting, it might be sufficient to know when an offworld-engendered civilization could plausibly have been active.

And it doesn't have to be Earth that we're talking about for that matter, it could be a game of exoarchaeology, but the same principles would hold.

Once we invoke aliens, all sorts of things become more plausible, even if we ignore superscience, magic, and psychic powers. For short lived colonies, just look at how long it took to prove "Vikings" made it to the Americas, and that was only a few centuries ago.

Re: Pre-human civilizations on Earth
Given that some of the items discovered from 2000 years ago look damned near like ore... Heck, the Titanic is turning to iron ore as we speak - rusticles a plenty.
Our mining of rich veins of iron &/or copper ores might be the remnants of silurian junkyards... ... I doubt it, but it's possible, given a million years of oxidative stress. |

Re: Pre-human civilizations on Earth
You have to prove not only that they are tools but that they are not human tools. The only way to do that is to prove that the control mechanism was not made for humans to grip(and even there that could only mean it is a coupling or that it used domestic animals). Or that it had voice command technology.

Re: Pre-human civilizations on Earth
They might cremate at a nuclear facility for all we know.

As I ponder it, I begin to suspect that there might be many orders missing from our knowledge even yet, and the further back we go, the more so. Esp. since even an entire taxonomic order doesn't necessarily have to be all that numerous in terms of member-species. That doesn't prove such an order existed, of course, but I don't think we can rule it out with any confidence based on the fossil record, either.

Re: Pre-human civilizations on Earth
Yeah, a given society might, but what about their ancestors and relatives?

Re: Pre-human civilizations on Earth
That assumes there are enough of them present to have variable funerary practices.
