I think the biggest controversy about the cosmological argument is: Do we have to have an explanation for everything that exists? This question can lead to many small questions, such as do we need an independent being to create all the dependent beings? Or, can all the dependent beings just exist as a group without an independent being? First of all, I think there is nothing wrong to assume that all the things that we know (water bottle, cars, planets and stars.etc) came to existence by the cause of some other things (which I think we can scientifically prove how the water bottle, cars, planets and stars came into existence). I think the problem here is not the causal relationship, but our lack of ability to conceive something that is infinite. Sure, we understand that when we say something is infinite, it means such thing (pi for instance) will go on forever. Then the point is, what is forever? Since we already have proven scientifically that the universe had a beginning and it was the big bang. Then the problem is: what's before the big bang? Is big bang the start? And if it is, then it means the universe has a beginning and thus it is not infinite. So although we can easily understand that every physical thing around us is dependent, which it does not create itself, we cannot perceive that such casual relationship goes on infinitely. I therefore disagree with the argument that "if we've explained the existence of every member of a collection we've explained the existence of the collection-there's nothing left over to be explained." In other words, I think the problem with this argument is that it assumes that all dependent beings can exist as a collection without a first cause. Well, first, we only know that dependent things do not exist in a loop, which means that the grandson does not cause the existence of the grandfather. Therefore, it seems that we can never use logic to find an explanation for the series because this series goes on infinitely. Furthermore, even if things do miraculously cause each other's existence in a loop, do they also require a spark to start the loop? And even if such a loop does not need a start,then is this loop itself an independent being? It seems that our logic does not work perfectly once we arrive at the problem of the first cause, which I think we always need to make exceptions to our premises. Whether we think there is an independent being or not, we just can't make a valid argument.
