We can date archeological finds accurately enough the the word guess is not appropriate. I know that sewn clothes have existed something like 20,000 or 30,000 years. And I think I read recently about woven fabrics dating back maybe 8 thousand years or so. I tend to think in round numbers so go ahead and call that a guess, but archeologists have this stuff dated pretty accurately. And new finds sometimes push the dates back even further.
