Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?
~Qur'an, 21:30 (Anbiya - The Prophets)
Yeah, I find the Big Bang theory to be very plausible within a religious context.
The Day that We roll up the heavens like a scroll rolled up for books (completed),- even as We produced the first creation, so shall We produce a new one: a promise We have undertaken: truly shall We fulfil it.
~Qur'an, 21:104 (Anbiya - The Prophets)
Perhaps the Big Crunch (and subsequent Big Bang(s)) are equally plausible.
The context for the chapter, by the way, is within a list of elements, natural and outcomes of human progress (from the orbits of the moon and planets, to knowledge of how to make chain mail, e.g.) that form the basis of belief in God based on reason and intellect. That's formed the core of my own beliefs, which is why I'm all about pushing for scientific progress. KF
