Question

How does discovery of fire and invention of wheel affect human history?

Answer 1

Fire wasn't really discovered it was controlled and harnessed. The tools to do that were discovered and improved over time from the tinder-box to the electrical impulse. Fire is raw energy.

Wheels were discovered. On in any event adapted. Likely rolling a log or a stone would have been all it took.

Fire, Water, Air, Earth are the basics that humans in their present and developed form need to exist and thrive.

Water which comprises the greatest part of a human was an integral part of us from dot. Air we breathed in and out to acquire oxygen to create energy and earth is where we took physical material to sustain ourselves.

Fire we learned kept us warm and allowed fiber in plants to be softened and made easier to eat. Later we used it for other purposes; to create energy for both good and bad; bad being killing and good being sustaining.

Man can live without a wheel, apparently the Aztecs did but he cannot exist in his present form without fire, or at least not for very long and not very comfortably.
