The quran states that the sky was made after life. However this is impossible due to to the fact that all water based life forms needs the biosphere in order to live.However some dont. Buth this is only few
, (from Greek bios = life, sphaira, sphere) is the layer of the planet Earth where life exists. This layer ranges from heights of up to ten kilometres above sea level, used by some birds in flight, to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometres deep. These are the extremes; however, in general the layer of the Earth containing life is thin: the upper atmosphere has little oxygen and very low temperatures, while ocean depths greater than 1000 m are dark and cold. In fact, it has been said that the biosphere is like the peel in relation to the size of an apple.
The development of the term is attributed to the English geologist Eduard Suess (1831-1914) and the Russian physicist Vladimir I. Vernadsky (1863-1945). The biosphere is one of the four layers that surround the Earth along with the lithosphere (rock), hydrosphere (water) and atmosphere (air) and it is the sum of all the ecosystems.

The story of Dhul Qarneyn states that Alexander travelled to the setting and rising of the sun. But he met people with no protection, this seems to be a condradiction stating the sky protects people. Even if you were to assume that they had no sky. They would of been killed without a sky or an atmosphere.
== Conclusion ==
Seems like the author forgot to mention what the sky does. Seems he took a guess of some sort by mixing an arabian and egyption culture. Stating the heaven protect the earth from something and mixes it with sky in order to give a puropse to the sky. But seems not to know that life needs a sky in order to live.
