I was thinking of a world in which no species of human ever figures out how to use fire. Fire still exist in nature but people never figure out that they can put it to practical use. In this world human history up until the time that people figured out how to use fire is exactly the same but for some reason people fail to figure out how to control fire or put it to practical use.
If people had never figured out how to use fire would humans have been able to eventually use electricity and electronic devices?
