Is Robin Hood Real?

Since we were talking about this in class, I googled it and got this link http://www.bbc.co.uk/history/british/middle_ages/robin_04.shtml. According to the BBC, "we would be fully justified in saying that Robin Hood was active during the reign of King John, but that his fame and popularity were such that within a generation his true identity had been obscured by legend." So we have no idea who he was, but he was probably a real guy. The article also acnowledges the impact of the forest, and the medieval game laws, on the legend of Robin Hood. Ironically, the king's forest, which was vast and protected for royal hunts, sheltered Robin Hood and his fellow outlaws. They used the king's own land to evade his game laws.
