Let me hit you with something that'll blow your mind: the Bible says that God has named every star in every galaxy and He has never forgotten a single one! Considering there are 400 billion of them in the Milky Way galaxy alone, and that the Milky Way is only one of billions of galaxies, you get the idea that God pretty much has to know who you are too, right?
Psalms 147:4 He tells the number of the stars; he calls them all by their names.
