I think there might be some confusion here. Let me restate my argument to see if it clears things up. I believe that if you can achieve precision tools you can use those tools to meet societies ongoing energy needs using renewable energy sources. This means that if you have non-fossil fuel energy sources available to advance metallurgy and toolmaking to the point you can make precision tools then you can reboot civilization without fossil fuels. I also think it is very likely that humans could do this but it might take longer than it did with fossil fuels.
