Every moving thing that is alive shall be food for you; I have given everything to you, as I gave the green plant.
Genesis 9:3 (NASB)

כל רמש אשר הוא חי, “every moving living creature, etc.” This expression includes all creatures other than man.
Tur HaAroch on Genesis 9:3:1
No. You can’t eat people.
