Yes, all humans are fallible, including Moses and the other authors of the Jewish bible, including the writers of the New Testament gospels, including Paul, including Jesus, including Mohammed, including me, including you, including the Pope, even including Shaker. Oh, hang on a minute. Here's my rule of thumb : the greater an idea's dependence on a single authority for its veracity, the likelier it is to be wrong. I think it a healthy mindset to acknowledge one's limits.
But Jesus was not just human - He was God made man.
"... and the Word became flesh and lived among us"
This is the whole basis of Christianity.
If I did not believe this, I would not be a Christian.
There is not the slightest bit of verifiable evidence to suggest that Jesus was anything but human, with the same faults and failings as the rest of us.
However he has obviously said something deep and existential which has got you rattled.
He's not obviously said anything, of course he could have existed and if he existed he could have said these things but the fact that he ever existed hasn't been established.
The words in the manual that professes to have recorded his words might be deep and existential, for bronze age, little more than goat herders.
