I think that Bertrand Russell nailed it:
"If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument."
(Although given progress in scientific knowledge since the 1920's, it would probably now be better to substitute "the universe" for "the world").
ICANT, you are using the English language to describe physics that can only be described adequately in mathematics which is so complicated, that only a small number of people on the planet are capable of being at the cutting edge of it. And then you say "this makes no sense". The words which helpful scientists use to try to help people like me who can't do the mathematics, are only ever an approximation - at times, they won't make sense, because they are being used to approximate a scenario which is so far beyond our daily experience as to be incomprehensible, outside of that advanced mathematics.
We can play games with the English words all day long. I could say that the universe has always existed. Because the word "always" means for all time - and one of the things that the singularity did was to start time. So because the universe has always existed, it never needed to be created - by anything supernatural or otherwise. That use of language is a fair one, and describes some of the science as I understand it. But it's pretty meaningless, because there's sod all mathematics in it, and therefore incapable of accurate dissection and analysis - we just end up playing linguistic and philosophical games, as the angels dance on the heads of pins.
At its most fundamental level, the concept of cause and effect is really just a reflection of our day to day existence. In the weird and wonderful world of highly advanced physics, analysing what went on in the earliest nanoseconds of the universe's existence, why should our unbelievably simplistic concept of cause and effect have any meaning whatsoever ?
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
