I agree, but even in our own history there was life before trees and I guess that's more of what I'm concerned. Other things are flammable but without substantial things like coal and wood they simply wouldn't really be able to make fires hot enough to be able to forge anything stronger than like...bronze? I guess that's also needing to consider atmospheric content and stuff. Sorry if it feels like I'm arguing with you, I'm absolutely not trying to, I just don't have people that like this sort of thing that are willing to or are knowledgeable enough to talk about it
