What Gemara? The nonexistant one that got edited out of the middle of Sanhedrin (maybe Gittin?) that to be factual as the way we have it would mean that Yushka lived over 150 years?
That is one possibility. Another is that the first author of the ‘nt’, wrote his book not 40 years after yoshke’s death but ~80 years after. Meaning that the Gemarah is right and the ‘nt’ is wrong.
There is evidence for this. For instance, an early church father named Epiphaneius also puts yoshke during the time of Yannai. There is a manuscript called Toldos Yeshu that Rashi quotes from. Although there are many different versions of this text today, certain elements can be found in them all, including this time earlier time frame.
