Very interesting Questions.
I will just say a little about Question 2 at this moment.
2) Do the ahadith or Quran or Islamic faith teach in creation of stars and planets from eternally existing matter (i.e. the organization of chaotic, but eternal matter, as some early christianity/judaism taught), or in creation from nothing (as some later christianity taught)?
