But that's how this Universe is. It is but an interwoven mesh of causality - of temporal moments that link each other almost seamlessly. However, when we regress all these temporal moments, we always beg the question as to what caused the prior etc - priori cause. That's why it's considered a fallacy of logic in Philosophy.
If you can accept this theory being circular logic and think about it carefully, then you will come to a conclusion that; ultimately we will need a truly atemporal and uncaused original existent (causer), state-of-affairs, or whatever you want to call it - (outside of this temporal causal existence). It really is a necessary solution to this logical problem. Wouldn't you agree?
What makes you think that there was a priory of anything? Is there any tangible –not imaginary non-existent beings such as Allah, eternity, infinity- evidence or example in given nature that shows or hints any a priory existence.
Just because it is considered as “fallacy” by human logic, it doesn’t mean that a creator, first cause, a priory beings must exist. Logic is not something that was carved into the deepest origins of universe, it is a human way to analyse things, and it exist in mind level, there is no particle for logic, or no tree out there that produces natural “logic” fruit. Human logic itself is evolving, what you find as logical today could not be found logical two thousands of years ago. And what you find as logical today is nothing but a thought exercise. Of course, if you are not using divine logic, such as Qur’anic verses or Cosmological Argument without checking out what is really going in Cosmos…
About astronomic knowledge we get from Qur’an:
-from Globes on Ancient Coins-The average person in Hellenic and Roman times knew that our
world is round. The philosophic inquiries and dialogs that began
with Thales reached their peak with Aristotle. Later, various
hellenistic astronomers made measurements of the size of the
Earth and the sizes of and distances to the Sun and Moon.
Pythagoras (who died ca. 497 B.C.) who defined his era with geometrical perspective must have applied his theories on any shape I assume.
Before them, even previous ancient civilizations like Egyptian or Indian had vast amount of knowledge about “heavenly bodies” –not your imaginary dream-like heaven. Because they were “measuring” and “observing” and illuminating themselves, they were not waiting for divine revelations.
Stealing this knowledge and selling thousands of year old human knowledge as Allah’s words are nothing but plagiarism. When Christians were trying to promote their God, they tried to cut off this information from their people; yet early Islamic civilization translated this and many other ancient –particularly Greek- knowledge into Arabic and they also observed skies. That’s why there has never been a serious “flat earth” theory among Muslim scholars when Europeans believed that earth was flat, and Bible even doesn't teach this kind of things, it was a political attempt by some Christians. Yet Muslims didn’t get this knowledge a priori from Qur’an; no, actually even Qur’an took this knowledge from ancients. Around five to six centuries ago from today, Muslim scholars also joined the club and stopped their curiosity due to some social historic reasons.
You didn't get the Big Bang, at least not the same way modern science got it. It took science hundreds of years and numerous observation to claim that everything in this universe originates (not "created", definitely not this disgusting word) from Big Bang. Science needed to measure the background radiation and related calculations in order to make this claim. Yet no one claims that Big Bang , or anything else for that matter, came from nothing. Big Bang must be originated from something else if everything else originates from something. I repeat: creation, art, philosophy, Qur'an, eternal, infinity, Allah, heaven are all the products of human imagination. They have nothing to do with real physical universe.
Now you are trying to sell us Qur'anic astronomy lessons which belonged to humanity long before Qur'an. Night and Day, orbits were all observed, categorized and they built pyramids on this knowledge. Since this thread is about Qur'an, why don't you come with other scientific revelations of Qur'an such as how did it guess the DNA or Atom. Bring the verses and hadiths...
