Sola Scripture - the only 2 assumptions are basically contained in this latin statement meaning God is not a liar and His Word contains all truth needed for mankind. The truth and meaning of the Holy Scriptures are self-explanatory and self-defined.
Just because they don't explain all the knowledge that mankind has attained does not invalidate them - this is actually done for our own protection from ourselves. In fact, it was the explosion of mankinds knowledge that caused the tower of Babel and it was by God's great mercy and grace that the languages were introduced and mankind disperced from one another - preventing their own untimely destruction through new technologies possibly even nuclear technology. Furthermore, Revelation states that the end-times will have to be shortened to also prevent mankind from complete and total self-destruction.
You appear to dislike technology, if this is so why are you on the Internet?
