Nietzsche can’t know what the Superman will look like—nobody can. But he provides a great deal of assistance: he is extremely insightful about what people are doing today (well, late 1800s, but still applicable), how that tricks us into behaving and believing in certain ways, and what that means.
But he wrote these insights as poetry. If you wanted an argument spelled out logically or a methodology of scientific inquiry, you picked the wrong philosopher.
