I believe that there is/was 'something' that created us (obviously) however the human mind isn't powerful enough to comprehend exactly what this 'something' is. For example, many people think 'being open minded' about a possible God is to say "it could be female instead of male!" which is just hilarious. I personally think whatever happened before the big bang, when 'nothing' came into 'something', there must've been a chemical reaction somehow, like the 'God particle' etc.
Which bakes the question: 'how could something come from nothing'? Like I stated in the 'Life After Death' thread, it's a prime example of a paradox that no one can figure out. Not even a genius like Stephen Hawking.
So any stance on religious beliefs is fine, each to their own! But I wouldn't personally gamble my short life on religion.
