seven skies in 71:15... how could old people know ?

[ilker]

assalamu alaikum folks,

According to 71:15, how could the people of old times, the people of Prophet Nuh (pbuh), think about seven skies ? How did they know about the layers of the atmosphere or seven layers of the universe ? Didn't they just see "a sky" over them ? How did they understand this ayah ?
