Why do we use Future Simple (will)?
Future Simple (will) expresses spontaneity. We use it to talk about decisions made at the moment of speaking. They are usually spontaneous decisions, such as offers, promises or threats. We also use it to talk about predictions without any evidence, such as hopes or assumptions. It is very common to make up sentences with 'I think...' or 'I don't think...', 'I'm sure...', 'I expect...' 'I bet...'.
