Why is a snake more closely related to a human than it is to a worm?

Well, I know one thing that could help you with your answer.. snakes are more related to us than a worm because of it's sheddable skin. Even though snake skin sheds regularly and with a large quantity, they are similar because we shed our skin as well. Worms do not shed skin like us and snakes. Although, they are able to shed their tails to escape predators, like lizards.

Because snakes are vertebrates like humans unlike worms who are invertebrates
