Those who Question the Oral Torah – the Word of G-d

In certain “Jewish(?)” circles, certain influencers have published videos alleging that the Oral Torah could not be the word of G-d because it is a series of disagreements between rabbis (i.e. this rabbi said this, but that rabbi said that), thus how could it be the words of G-d from Sinai, if it is a series of disagreements among men, etc. etc.

Similar sentiment has been echoing elsewhere on social media from anti-Semites (I know, I know, do not listen to commentary in Judaism from social media) which uses the famous Talmud story of G-d saying “My children have defeated Me” in reference of the Torah not being in the heavens but on earth. The individual posting this concluded that this was an attempt to consolidate power among the Rabbis, to basically make the point that their rulings is the word of G-d.

Now because my faith is so strong, I have no problems asking questions – as is the Jewish way. So I ask you, in this case – the common allegation is that, G-d forbid, the Oral Torah was corrupted by the rabbis for the sake of inflating their own authority, which we all know is a blasphemous statement. But the logical paradox is interesting. How could the disagreements of humans be the word of G-d? How could a Divine and Perfect Scripture, the Torah, be in the earth for others to “decide”, not in the heavens?

Thank you and I look forward to reading your replies.
