Still think there’s like a 10% chance there has been a past advanced civilization on earth that was responsible for one of the planet’s large-scale mass extinctions. A good candidate time period is the Great Dying.

Very little from this era survives, and if the technology of the time were not based on metals we’d never find much of a trace. Heck, even if it were based on metals we’d still have trouble.
