Creator of God, Big Bang

I have a question:One thing I have noticed is that creationists like to attack the big bang. Which of course we have minimal knowledge and proof of. They attack with statements like, which apply not only to the big bang and the universe, but also about life etc. "How can you get something out of nothing?" and "where did matter come from?" .. "there has to be something out there..."My question is who created God, or how did God come about?Now I know the answer is he wasn't created, he has always been there..However doesn't this throw the whole argument that machines require an engineer out the window? Humans cannot arise by chance, but a God with infinite power can?Creationists can only say that is what we are told and believe.Evolutionists can only say upon studying it, we think that this is what happened.But logically I think that a cloud of hydrogen gas coming from no where is more believeable than a super God coming out of no where.We will almost certainly never know how the universe came to be, so it is unfair that creationist scientists say that living things can't come about on their own and require active thought to make because this falls apart at the very start with the "God that just was there"I hope I have succeded in getting my point across and would like to be educated if I am wrong.many thanks in advance

ok, I suppose I didn't really know what to expect with this topic.I understand that the whole question of how the universe began cannot be given an answer and it 'just exists'. Apoligies if this is kind of an irrelevant thread.I am just fed up of creationists telling me 'you believe in evolution, ok. Where'd the world come from? where'd matter come from?, where did the stuff your made of come from?' and i'm like 'where did your God come from?'the response that this question is not applicable to God and has just always been there in another dimension is not a satisfying answer and cannot be trusted without some kind of evidence.and that the 'creation demands a creator' makes no sense anymore since they are basically saying that God didn't need to be created. Just like I think we didn't. Thus, indirectly believe in evolution themselves.So God must have come about by some evolutionary process also.
