how do i convince my brother he is adopted?

It is difficult to convince someone that they are adopted without any definitive proof. You could try to gently broach the subject with your brother and tell him that you have always been curious about your family history, and would like to find out more. Maybe he will be open to talking about it and have his own questions about his family history. You could also do some research together to help jog his memory, but be careful as this could be emotional for your brother.
