As explained in the Talmud (Sanhedrin 58b), they include the prohibition against theft, murder, and sexual immorality.
These are the pillars of human civilization, and are named the "Seven Laws of Noah," since all humans are descended from Noah.
The other alternative is to pursue conversion to Judaism.
This is not simple, given that you will want to make sure it is "kosher" from a Jewish legal perspective.
The conversion process must be done before a court of three Jewish men who themselves believe in God, accept the divinity of the Torah, and observe the mitzvot.
In the case of someone who denies fundamental principles of Jewish belief (such as, the word-for-word divinity of the Torah), or offers to perform the conversion without requiring full mitzvah observance, the conversion would be invalid according to the Code of Jewish Law.
It appears there are two options for you right now.
If I date a Jewish girl, will her family not want her to marry me because my mother is not Jewish? It appears that your confused identity is a tragic result of intermarriage. The Bnei Noach are people who have a very "Jewish" feeling, but are not Jewish.
I have half-brothers and a sister who are totally not Jewish. For example, see this article: com/jw/s/80405497To learn more about the origins and ideals of Bnei Noach, see an excellent book on the topic, called "The Path of the Righteous Gentile," by Chaim Clorfene and Yakov Rogalsky.
As you could imagine, this would create a variety of confusions regarding the person's religious identity, and that of their children.
And in your case, this would only further complicate things.
