All well and good but everything posted so far is OPINION . . nothing more, nothing less.
The one thing that is absolute fact is that we will never know for sure what happened. You are all talking in human terms: 'matter' etc What if it was some 'bloke' (I use the human expression) sitting on planet zog who did something with something for which there is no known human equivalent and OOOPS, there was a big bang. This airy fairy explanation is 100% as plausible as the most learned theological or scientific theory. Why? Because it is beyond our comprehension, that's why. Lets face it: Your 'bible', whichever flavour you subscribe to, is just a convenient collection of stories (anecdotal evidence if you like) that was put together over centuries, passed down from father to son, to try and explain the unexplainable. That does not make it fact. Therefore: Religion doesn't have the answer, only an opinion.
Now, before the inevitable thunderbolt hits (be it from the east, west or the heavens) can I also blow apart the scientific explanation:
So there we were (oops, already asuming that there was something existing) sitting in what would soon become known as space when 2 things (be they gas, atoms, or gronks from the afore mentioned planet zog) crashed into each other to cause a big bang. So what created the two things? (To spare you an infinitely looooonnnng series of questions let's just stop there.) Being infinite, there is no getting to the start. Therefore: Science doesn't have the answer either, only an opinion. Admittedly it's a bit more believable than stories of a naked bloke in a garden but it still relies on there being something at the start . . . . . but who made it?
There is no arguing with any of the above. Neither view stands up to rational discussion therefore We win. Lets go down the pub and celebrate!
PS I only came on this site to find out why my car is vibrating? Funny old world
