in Verse(41:12) Allah was describing the sky/heaven as the invisible path (not the planets and stars) that it was just a chaos (maybe just one chaos path/sky, maybe more) of a mixed up smoke/gas...etc. when he finished making the earth ready for life,
then I believe that he separated smokes from each others to make something new, and Tided it cosmically into 7 a layers above another, and each one of these paths have it's own special component, properties, and job .
I.E. earth atmosphere layers, who tided them into above another layers ? can atheists answers us who tides the earth's heavens/skies into a different layers and how each one of them have it's own job?
the one that tided the earth atmosphere into layers, and ground into layers, can't he tide the universe sky into 7 heavens/layers/paths above another, and make each one is different than the other? like the salt water and sweet water seas.
