Who is the most influential person in the history of being

[Warpy]

6. The first anonymous women who played with grass and a stick

and discovered how to spin twine.

From that, the bow method of making fire arose.

Stone heads could be firmly affixed to shafts for arrows for bows strung with twine rather than sinew, meaning larger prey could be killed and diet improved as twine was cheap enough that the loss of a few arrows would not be tragic. Spear heads were similarly affixed.

People could move out of dank caves into tents, either woven or of animal skins held on sticks stabilized by grass twine.

Twine was used for primitive foot bridges across streams, increasing territory. Sinew had been neither long nor strong enough.

And this just barely scratches the surface of what spinning and textile arts have done to improve human life. Peoples who discovered spinning tended to progress technologically while those who didn't did not.
