Its not fundamental to belief unless your belief is that the Bible is the perfect Word of God with absolutely no error in it.
Even the fundamentalist Christians that believe the Bible is literal do not believe it is absolutely perfect with no errors.
I have found that other than errors in scientific knowledge (which I do not take to be critical to the meaning of the Bible as its author's originally intended), the text offers few unintentional conflicts. Sometimes its very terse language creates a perceived conflict.
The bold needs further explanation. Science is of course, not without errors, but the there is system of Methodological Naturalism, which is very functional in evolving science to eliminate errors, and increase the knowledge of science.
Errors and conflicts in the Bible are not intentional, and those that compiled the books were sincere in their efforts, but simply reflect the view of those that edited, redacted and compiled ancient texts of various sources to come with the text of the contemporary Bible.
The biggest problem with the Bible is that it is fixed in history as scripture and has limited context outside the culture and times they were written, and the conflicts with science are too much to resolve by interpretation.
