Well im not quite sure but when reading that question the first thing that pops in my head is that they can be imaginative, and create great ideas.

In Scout Momaday, said on page 3, "The young Plains culture of the Kiowas withered and died like grass burn in the prairie."
Similes use like and as to compare someone or something and a metaphor doesn't.
Example of a metaphor: Her hands turned to ice in the cold wind of the Autumn.
Your hands only felt like ice and didn't actually turn to ice.
