If two notes can be referred to as the same thing, such as F# and G-flat, why do we have two sets of key signatures, those being flats and sharps?

Wouldn't all the notes be covered, therefore you'd just use one set of key signatures? Whats the point of the flat key signatures? Maybe I am misunderstanding but getting a grasp on the logic would be much appreciated.
