It is because the meat eating dinosaurs hunt things that move. When we sleep, we don't move all that much, which allows us to effectively hide from the dinosaurs.

Quantum Apostrophe: Sort of like you grasp the difference between the Earth's air, gravity, water, pressure, temperature and the deadly emptiness of space?

Funny thing, with my multicellular, eukaryotic brain and hands I can fashion a pressurized steel container to travel through that emptiness in all the comfort and safety of home. Alas, poor E. coli is stuck here on Earth, probably inside a cow intestine, and couldn't even grow eyes to see the stars because eyes are multicellular constructs. But it's immortal, so that makes it all better. Unless the cow craps it out and it dries out and its proteins denature and its cell membrane ruptures. Poor E. coli cell! All alone in the world. Not even fellow specialized organ cells to keep it company. Bye-bye, little prokaryote! We hardly knew ye!
