I see the same thing in many of your posts, and I agree with you, these things happened long ago, and God had many these events written down for our admonition, in my view anyway.
I understand the philosophy you refer to here. And truly, many disregard God's Word because of the same reason you posted. And truly men have worked to influence the Scriptures. But for me, I'm not convinced that God is not capable of preserving His Truth through the Scriptures. Paul trusted them, Yeshua trusted them, Peter, Zacharias and Simeon, in Luke 1&2, trusted in the Scriptures.
For me, surely God knew about the Bibles we have when HE promoted the Holy Scriptures through Jesus and His Apostles.
So while I understand your point about the Scriptures, I also believe that God is able, and actually did preserve His Truth in them "
for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works".
Again, I appreciate your views, but Paul was accused of teaching against the Laws of God. Here is his response, (I know you know the Scriptures, but it is my practice of posting them anyway, for those who may not, I mean no offense to you)
Acts 24:
13 Neither can they prove the things whereof they now accuse me. 14 But this I confess unto thee, that after the way which they call heresy, so worship I the God of my fathers, believing all things which are written in the law and in the prophets:
His Word in me, Speaks to me every "Now" that exists throughout the day.
