“ My question is 'Is there any proof anywhere in history where Jewish or Christian people lived their life according to the Scriptures?"
Uncountable numbers of people have endeavoured to live their lives according to Scriptures. I would cite the family of Jesus who made the sacrifices, observed the festivals etc of the Jewish scriptures. I can’t imagine Joseph being unscrupulous in his dealings with others . In the early Christian world a lot met their death in the arena rather than violate their beliefs .
Today millions of Christian people believe they are living the right way , the trouble is the application of Bible principles. e.g. A JW would not vote or stand for office because he must be “ no part of the world “ . However , a Mormon may tell you that it is Christian duty to do so , for the good of the community.
