It doesn't matter either way because the talmudic teachings has been the foundation that shaped jdaism for millennia.
You can quibble over which came first, the chicken or the egg or if jdaism's most respected religious scholars and their lives were fictional characters created by the pharisees, but it doesn't change anything meaningful: the talmud is still the talmud and jdaism is still jdaism.
If you can prove the rabbis scholars of the talmud are fictional characters created by the pharisees and those teachings are not based on teachings from early jdaism... then go ahead. I'll wait...
Do you think pharisees just made that up too?
