Fossil evidence indicates that there have been several Homo species who rose to the point of being tool users before their demise. Therefore the emergence of a technicallogical species on Earth is not unique to humans. Given the long history of life on this planet, is it possible that other creatures have evolved into a tool-using race in the far past? After all, humans have been here for a tiny fraction of the planet's history.
Three billion years is a long time. Time enough for many civilizations to come and go. Would subduction and erosion be enough to eliminate all artifacts from a civilization from millions of years ago?

You make some good points. We have fossils going back over a billion years so any civilization comparable to ours would show up somewhere. In addition, an industrial civilization would have depleted natural resources in much the same as as we are doing now.
Still, i cant help but think that 3 billion years is an awefully long time. Perhaps another species rose to the height of hunter-gatherers with stone tools and was then wiped out in an extinction event. We may never know.
