Are 'Discourse on the Method' and 'Meditations' different books? If so, which one is better suited for an assignment which asks to explain the proof of his own and the God's existence?

The *Discourse* was intended as the introduction to three science books but is nowadays mostly read on its own. It is great because it is very short and introduce many important themes in cartesian philosophy. In here you find the famous *cogito ergo sum*.

However the *Meditations* is the book where his metaphysical/epistemological system is more fully developed and it's what you should probably read. Since it is the first peer reviewed philosophy book it also often come with an appendix of objections and answers which is important if you're a scholar but that you can easily dismiss. It's a bit dry but it is easy and fairly short as well.
