>>14380240>Is Judaism different from Hebraism?No, the Oral Tradition was present since Mount Sinai and even before arguably (the Written Torah doesn't specificy what a kosher slaughter looks like, while the Oral Torah does as it was something passed not in a written way, but in a practical and oral way)
If you still have doubts about the Torah in general because of science and academia, you should study the historical fails of science and history, study the dissenters and what religious jews say about it (as many religious jews also have phds in natural sciences and the like). Then you weigh the arguments and form your opinion. My opinion is that science and specialy history (
