The term "blind" just means no evidence in that case. That is why they are called religions, it is pretty much the definition of them-- there is no historical or scientific evidence of the Bible-specific events of the Bible, especially the Old Testament, just as there is none for the religion specific stories of Ra, Buddha, Zeus, Vishnu, Xenu, etc.
People who want a religion chose the one of the hundreds/thousands of religions that they want to believe in by faith, definition 2 above.
It is not scientists' or historians' jobs to disprove religions, it is adherents' job to prove their religion, if they feel they need to. Most just write it off to faith and mistranslations or misinterpretations when something in their religion does not fit the scientific or historical evidence (e.g. 6000 Year-old Earth with an Earth-wide flood in that period), which is fine. Literalists dig in and become denialists like the wackadoo Ken Ham.
