Are my brothers and I citizens automatically through the child citizenship act of 2000? My dad was naturalized on 2004 but we were born before that.

Under CCA, your child will automatically acquire American citizenship on the date that all of the following requirements are satisfied: At least one adoptive parent is a U.S. citizen,The child is under 18 years of age, If the child is adopted, a full and final adoption of the child, andThe child is admitted to the United States as an immigrant The Act became effective on 2/27/2001, so the child must have turned 18 after that date.
