I heard that there is something called Seerah. Would you kindly tell me what it is?

Generally speaking, Seerah means the life history of someone. Any time Muslims talk about the Seerah, they mean the biography of Prophet Muhammad. Muslims are to study the Seerah of the Prophet so that they will be able to imitate him, emulate him, and benefit from his wisdom and his teachings. The early followers of Islam have written a series of books about the Seerah of the Prophet Muhammad to act as a guide to all the new generations to come.
