In Quran Muhamad does not say who created light, clay (soil), water, Angels (but in Hadiths, Aisha says Angels were born out of light.)
If Allha is light, Angels cannot be. If not Angels would be almost similar to Allah with very little diffrence.
Poor Muhamad, he did not have a computer.
He was well literate, but in order to show and prove that all the verses are form Allha, he cunningly claimed that he was illiterate.
Poor man had to Mostly hide himself form others, when he was composing his verses, may be writing in the sand until he memorized them. But lately he only composed small verses, when he became involved with his companions and was busy, where he could not go to Hira mountain to have a look at the Jewish scriptures to get ideas and to compose long verses.
