The answer
Yes, angels were created before Adam and Eve. St. Augustine says, ‘Although the Scriptures do not tell us exactly when the angels were created, from the sequence of creation we can tell that the angels were created under the name of "Heaven," when it is said, "In the beginning God created the heavens and the earth."
