Hi Kai Hagbard,
I'm glad you found my post informative. Firstly I cannot explain the science behind the shooting stars and the devils. However, just because one cannot explain one can't just assume it to be wrong. Secondly the evil jinn is referred to as a devil(shaytaan), not all jinns are evil. Similar to human beings some are good and some are bad. Infact jinns are also created to worship Allah just like humans. More research may reveal more answers.
Take care
