Question

Hello, honorable Rabbi.
I wanted to ask a preliminary question בעקבות reading several answers on the site. So, assuming we have become convinced that there is an intelligent entity in a different dimension that planned and created the world, what would obligate me as a Jew to conduct myself as a Jew? After all, we would also need to prove the revelation at Mount Sinai and describe what exactly happened there. I would be glad if the Rabbi would address this issue.
