Welcome to Android Central! Has this always been your phone, or did it belong to someone else before? If you never set up your Google account on it, then it's possible that a previous owner did, and the phone is asking for that person's Google account and password. That's Factory Reset Protection, which is intended to discourage a thief from stealing a phone and doing a factory reset to make it their own.
