A day without fire story
Answers
Answer:Without fire humankind would’ve only had the moon and stars as a light source at night. In a cave, complete darkness. No Palaeolithic art, and no culture (not counting burials) for us to discover. Perhaps humans may have developed a better visual system for seeing in complete darkness (unlikely because of daylight.
Without the wheel humans would be restricted to dragging, or rolling large objects. No chariots, and therefore no carts. What a grind. Rollers of wood may have been used but someone surely would have twigged about cutting it down and making a wheel. I believe the the Americas (Incas, Aztecs, Olmec, etc) did not have the wheel - check their civilisations for the impacts. North American Indians had travois for dragging loads about.
Without iron people would have been stuck in the age of bronze, a softish metal. As long as everybody was on the same page, and didn’t have access to harder weapons, I suppose this wouldn’t have mattered militarily. But without iron humans would not have advanced any further than the so-called dark ages. No nails, no rigid long metalwork, no fine engineering or Industrial Revolution.
There are probably numerous other lines of blocked inquiry for humans without iron.
