"Don't the disbelievers know that the heavens and the earth was as a mixed mass were and that We split them up after and that We made all living organisms from the water? Don't they believe?" (Qur' an 21:30).
When we look to the first moment of the "Big bang", then we see that there was a point that contained all mass of the universe, its name is the the cosmic egg. Everything, even the "heavens and the earth" that are not created yet. We where together in this point in the form of mixed mass. After that the cosmic egg exploded, all mass split up.
When we compare the expressions in the verses with the scientific discoveries, we see that they are in perfect agreement with each other. Interesting enough is that these discoveries are done in the 20th century.
"After that has He directed to the heaven that was smoke (on which He said till him and until the earth) : "Bowl willing or unwillingly!" They said: "We come willingly". (Qur' an 41:11).
The modern applied and theoretical cosmology gives clear at that on a particular moment the entire cosmos was nothing differently than a 'smoke' cloud. This is one of the unquestionable principles of the standard modern cosmology. Scientists can observe now new stars formations in the remains of these 'smoke'. The clear stars that we see in night, were just as the whole cosmos formed in these 'smoke'.
