This is a common counter-argument from Jews, but to be frank, it only demonstrates profound ignorance of the Talmud. The Mishna is just as much people's opinions and even sometimes them arguing. Look at the very beginning at
https://www.sefaria.org/Mishnah_Berakhot.1.1?lang=bi:
"From when do we recite the Shema in the evening?
From the time the priests enter to eat their terumah (a consecrated offering), until the end of the first watch: these are the words of Rabbi Eliezer.
But the Sages say: until midnight.
Rabban Gamliel says: until the dawn rises."
Moses told them what Rabban Gamliel and Rabbi Eliezer were going to say and that was passed down as an "Oral Torah"?
