Sometimes I wonder if humans or another species millions of years ago had technology as good or better than what we have now that was just biodegradable which is why we haven’t found evidence of it.
You should read up on the Silurian Hypothesis. It’s a fun scientific paper asking whether, if another intelligent species had arisen on Earth in deep time, we would be able to detect it. One of the most promising theoretical signals might be unexplained carbon spikes…. Very little other evidence could be expected to endure.
No reason to believe it’s true, hard to prove a negative, etc etc, but it’s fun to think about.

That’s a fun idea.
