I think it's important to note that Big Boss in this game has a prosthetic hand. There is never any mention or reference to this in any Metal Gear game that takes place after this one. This is a major retcon and shows how loose Kojima can be with the backstories of main characters. Everyone here who doubts this is Liquid snake is trying to take all the disjointed facts of Liquid's backstory as absolute truth set in canon stone.

For me, the tagline "a youth who curses his fate" is what sold me. The British in the hospital where Big Boss was in a coma is also a major hint in my opinion.
