Miracle

In comparison to you, I am confident in stating that up until fourteenth century no one has the knowledge about numbness.

If you are an honest person then in place of playing with words just bring one solid statement of some renowned person who lived in seventh century or prior.

Numbness is a feeling that can occur when someone receives 3rd and 4th degree burns.  It's a feeling brought on by a physical injury, it's not like a scientific discovery.
You saying people discovered numbness caused by burns in the 14th century is like saying the blister was discovered in the 2nd century BC because that's when someone first wrote about it.
I assume ancient people knew that being hit in the groin with a rock hurts, that they knew that scabs cause skin to go numb, they knew fire caused hair to singe, I might not be able to google search any of these things and find them but I assume ancient people knew of them because they're feelings related to what an ancient person would almost certainly have experienced.
I have absolutely no historical proof whatsoever that ancient man knew scabs caused skin to go numb, but it's completely logical for me to assume they did know since they would have experienced scabbed skin, they would have experienced 4th degree burns.
It's the same principle.
You're citing as proof that NO ONE in ancient times knew of numbness caused by burns by telling me 6 ancient philosophers never wrote about it.

By your logic I can prove no one in ancient times knew that being hit by a piece of wood in the groin hurts unless you can provide me an ancient historical statement about being hit by a piece of wood in the groin, find me one statement.
And I can prove no one in ancient times knew that scabs are numb, unless you can provide one ancient source.
