Answer 2

Answer:

Without fire, I could only have relied on sunlight as a light source. Also, there would be no food cooking source. Without the wheel, there would be no car, motorcycle or bicycle and humans would be restricted to dragging or rolling large things. Similarly, iron is the most important metal in today's world.
