ELI5: If pasta is made of the same things (flour, egg, water), whats the point of the dozens of shapes?

It's about the sauce. Sauces cling on to each shape differently. Lighter sauces coat long pastas well. Tube shaped and ridged pastas work well with thicker sauces because they can pick up the sauce better. Buttery sauces are best with filled pastas. There are many great online guides. You should check them.
