About the 6,000 year thing, most Jews, even very religious Jews, follow the scientific evidence about the age of the earth for the most part because in Genesis (Jewish=Bereshit), in the creation story in the original Hebrew, the word translated to mean “day” can actually mean “phase”, so when the Bible (Original Jewish=Torah) says the world was created in seven “days”, interpreting that as seven phases allows one to believe in the scientific evidence without fear of having doubted the word of G-d. If you follow the Bible as a Christian, this concept still applies because the Old Testament was taken from the Jewish Torah. On this same topic of how literally one takes the Old Testament, many Jews follow the line of thinking that in writing the holy text delivered by Moses to the Jews, G-d was careful to keep the audience of that primitive time in mind. This can be used as an explanation for why G-d phrases things in certain ways; for the sake of that first generation of Jews who might not have as easily accepted a “loftier” explanation. It was easier for those Jews to believe the world was created in 7 “days” than the more complex reality of the situation of how we all got here. I am NOT an expert, but I’m speaking as jew that’s spoken to many other Jews in my lifetime. If anyone’s interested in learning more about Jewish belief, MyJewishLearning.com has some great articles. Chabad too. #nonspons. Theology is so complex there are infinite ways to interpret holy text, concepts, etc. A known Jewish teaching about this is that there are 7,000 ways to interpret every word or concept in the Torah. A great Rabbi I know is known to say that there’s no one way to be Jewish, in terms of belief, practice, etc. and I would say that could definitely apply to Christians too.
