Is the decomposition process discovered in 1920, which involves recycling matter from the death and decomposition of living organisms to turn into plants eaten by animals, what was referred to in Quranic verses such as His saying, the Almighty: "He originates creation and then repeats it"?

The meaning of "begins the creation" is the establishment and origination of creatures from non-existence. And "He restores it" means bringing them back to life after their demise and decay, just as He originated them the first time. This is easier for Allah than the initial creation. These verses have no relation to the process of decomposition, for the Quran is a book of guidance, not a book of sciences.
