ברכות מט,א

The Sefer Amudeho Shivo explains why we say Alenu after a bris. Simply we say יוצר בראשית to remember that Hashem created the world for the Jews sake and the bris differentiates us from the goyim. He gives an interesting reason. As we see that the kosher animals are physically different than the non- kosher, so why shouldn’t the Jews be born physically different than the goyim? Then, we would say their are two reshuyos, two deities on for tor the Jews and one for the goyim. Therefore, a bris is a proof for having One G-d, so we say Alenu to substantiate the Uniqueness of Hashem.
