The Sages address the question of why the creation of the first person was formulated in the plural, “Let us fashion man,” despite the erroneous conclusion one may make from such wording.

When Moses was writing the Torah, he would write what was formed on each and every day. When he reached this verse, which states: “Let us fashion man in our image, in our likeness” (Genesis 1:26), he said before Him: Master of the Universe, I wonder: Why do You provide grounds for the heretics? He said to Moses: Write, and let one who seeks to err, err. The Holy One, blessed be He, said to him: Moses, this person that I created, won’t I establish both greater people and lesser people from him? If the greater people will come to consult with the lesser people, and will say: Why do I need to ask permission with one lesser than I? The lesser people can say to him: Learn from your Creator, who created the heavenly and the earthly. When He came to create Man, He consulted with the ministering angels. (Bereshit Rabba 8)
