The sentence I'd like to ask is from
athe novel "Farewell Summer" written by Ray Bradbury. (I changed the article from "a" to "the" because you are discussing a specific novel)
Grandma stepped into her pantry and felt the wind blowing from the west.
The yeast was rising in the bowl, a sumptuous head, the head of an alien rising from the yield of other years. She touched the swell beneath the muslin cap.
It was the earth on the morn before the arrival of Adam.
It was the morn after the marrage of Eve to that stranger in the garden bed.
Does "stranger" mean Adam? I would say so because, according to the Christian Bible, there were no other people on the earth at that time.
I wonder why he suddenly mentioned about Adam and Eve after describing the atmosphere of the pantry. The writer is trying to show an image of something new and fresh. As to why Bradbury wrote this way, you would have to ask him.
