Well, Aren't They?

Kinda, but they come with an ancient curse or some other gimmick

You don't turn into a mummy if they bite you

Moisture content is totally different

I thought that mummies were supposed to retain some intelligence

Mummies have no brains, heart, lungs, or anything really past the trachea... that and they're saltier than uncle Jim's jerky, and more dehyrated than that weird piece of astronaut fruit you had as a kid.

mummies kill people zombies eat people

Someone give Sheldon a cookie.

Also mummies are real and zombies aren't. Mummies don't come to life but they are real.
