If there had been a technological civilization before ours we would notice the depletion of natural resources, especially metal ore and fossil fuels.

The sad truth is we only have this one shot. If we collapse, there is no way another civilization reaches our technological level. All the easy to access fuel and resources have been pumped and used, so they wouldn’t have the energy and materials required to start industrializing. They’d be stuck on a depleted planet with no realistic way to escape it.
