Fossil fuels are a renewable resource on the geological time frame. They're not use once and gone forever. Most of the oil we know of today was formed in the Mesozoic and later. So after the Silurian. In fact, suspiciously, only a small percentage of what exists today is assumed to have been formed in the Paleozoic. If anything the notion that they'd have used up the fossil fuel only supports the idea that such a civilization may have existed, if anything. But of course one can also point to the simple fact that we're already transitioning to renewables and we're far from being short. We just do it because it's better. So why couldn't a past civilization have done the same?
