I have a lot of প্রশ্ন about Groot and Rocket mostly about their origin?

Groot's origin was that his family were annihilated দ্বারা Ronan, leaving him an item that can restore his people. Rocket was just a raccoon when he and his family were abducted দ্বারা robot scientists who plan to further evolution. They both met on the same planet when they were both prisoners.
