יש”ו as is written in the Gomorrah is not a name its an acronym for ימח שמוו וזכרו it never was a name they took it as a name.
Regardless the one in the gemorah lived 180 year before they claim their guy lived so they can’t be the same.
In fact the ones who write their Bible never saw the guy at all so basically their Bible is all hearsay.
Basically there is no proof the guy they claim ever lived
