It's not that difficult. God gave the story of the creation to Moses in revelation. Moses wrote what he saw. God didn't tell him what to write.
Gen 1 does reference to the creation of clouds, 1:6 mentions the expanse and the division between the waters and the waters. That's the clouds. And in vs 14 speaks of luminaries. The luminaries of the sun and moon were created at Gen 1;1 so this speaks of the clouds letting them be seen from earth so clouds were there.
What confuses people is the days thing. But time was not mentioned until Gen 5:3 "Adam lived for 130 years and then became father to a son". That was the first occasion that time was mentioned. The days came later.
