How the hell did I miss this topic?........well In the end it boils down to one thing - something has to be acausal (existing forever)...atheists believe it is the universe itself while theist believe it is GOD.(argument of creation)
I prefer being a theist. I hate to divert from christianity but on this point ; the descriptions for the time and nature of creation of the universe closest to the ones given by modern science are found in Hindu philosophy.
I will try to explain ;in short ofcourse; the more basic and abstract version of creation as explained in the vaayupuraana, whichis closest stuff to big bang theory..!
The section between the comment marks (/*....*/) is my opinion on that particular verse.So here goes:
The Avyakta (the unexpressed/ unrealized) entity which itself is the kaaraNA (cause) of everything resides in the sat and asat form (true and untrue form OR percievable and unpercievable).
/* This coincides with the modern theories in theology about the origin which culminate in the opinion that there has to be something that is acausal; either the universe itself OR the creator of the universe. Atheists chose to believe the former while theists believe the later. */
This Avyakta is devoid of any attributes of any kind like touch, smell, sound, sight.
It is Ajanma(unborn), Akshaya(undestructible) and dhruva (fixed / always existing).
/* This is what is referred to as Parabrahma */
In the aa***aala...this was all that existed. And since it didn't have any attributes, it was also devoid of any Guna (Satva, Rajas Or Tamas) hence there was no reason for its perceptible manifestation.
/* Because these three Gunas make everything perceptible...in either "good" or "bad" way. Good or bad being totally subjective terms */
The Sa-Guna entity which is manifested from this Nirguna condition is called Mahaan. It is created when the Avyakta realizes itself.
/* This is a tricky part...according to me it means thus:- The Avyakta is the source of all the souls in the universe but it has blended everything into itself so that the Gunas which are responsible for all the tendencies towards any activity (be it "good" or"bad"), are blended onto themselves. so there is nothing to percieve and noone to percieve because all that was percievable is existing in the Avyakta itself. When the Avyakta itself "realizes" this condition, it means that there is a mean of realization i.e. some Guna has manifested albeit the cause is the Avyakta itself. Thus the Avyakta "chooses" to be manifested. In short, The universe is created on the whim of the universal mind! */
.: Vaayupuraana Section ends here :.
The stuff after this is even more complicated...so I'll avoid that. But it can be seen that the cause and the fruit of everything is that universal entity (GOD if you prefer) which decides everything that happens. And you cannot know why you were created or why the Avyakta chose to go from an orderly state to a disordered state ( similar to entropy concept in modern physics) ; unless you rise to the level of realization of the Avyakta.
So forming theories about why you came into existence and why you should or should not suffer because of your karma is futile unless you rise to the level. You can never comprehend the purpose of creation of the universe by the application of mere logic.
