What kind of loon do you have to be to think that a question about the difference between comets and meteorites falls under the heading of Spirituality and Philosophy? That's a question for science and the answer is well known, and the Quran doesn't get it right if Nassir's citations are any guide.
The loon in fact is you, Dexter Sinister.
I have posted this thread here, because I am certain that you and some others like you will push it by any means to this spirituality forum.
Therefore, it is useless to post it in another forum.
Moreover, your view of this subject is not scientific, which is the insisting on rigid explanations even though they are not logical, and even though there is a better explanation.
