So the idea of worlds like this has been brought up a few times, about how human technology would have developed without fossil fuels, but the question I have is whether it is plausible for a world like this to develop. Could humans(or human like aliens) evolve early enough that there is not actually a reserve of fossil fuels?
To clarify, I'm talking about this issue from the perspective of geology and biological evolution, not human technology. Given the long timeline of life on Earth before humans, which was responsible for creating the deposits of fossil fuels, would it be possible for a group like humans to have evolved early enough that fossil fuels never fully formed?
For the purposes of this question, I'm not wondering about how tech would develop, just about whether this is plausible as an evolutionary history on a planet like Earth.
