Your comment is full of self-righteous certainty and arrogance. You assert that you would design things better if you were a designer, a major assumption. If humans and pandas were designed by an entity, you have no idea what their thought processes were; there may be more complex reasons for the way life forms are designed than you have knowledge of. You simply cherry pick examples of how certain things can be seen as "stupid" when viewed out of context. This is a childish argument. Your smug dismissiveness is not persuasive.
