Some points favouring Atheism , can they not br true?

So me myself is a Muslim , i just wanted answer and explanation to this just to strengthen my Iman , So basically one of the most major point used against Atheism is that everything needs a cause , a thing can not exist itself , and something must would have created it , everything has a cause which furthur has a cause and furthur so on , we go back and back and back, and there must be a first cause that is what we call God , to a normal person this must make clear sense and upon thinking he must come to conclusion that there is a God that has created literally everything , me myself believe this , But heres the thing , I recently searched upon this topic and got to knew something , which made me go into a doubt , So , according to science the earliest known moment is the Big bang , the expansion of the universe , which is said to be the start of the universe , but upon thinking a person would surely think that how could big bang occur itself , such thing must also have a cause , probably God , so i searched upon this thing and read that this all system that a thing can not exist without a cause , this whole concept ,it is only for normal and everyday things , on Earth and in Life , we think like this because everything in our surrounding requires a cause, making us think the same for the whole universe , including things so far in universe and so back in time , including the big bang , .... , it is said that when we go so far from this world , far in the universe , so back in time , the same rules of this world do not apply ..... For example .... The Quantum Physics allows some things (tiny) to exist without an actual cause , may be that could be the start of the Universe, moreover there are also a lot of other changes in Quantum physics conpared to classical simple physics , ... and Also the Concept of time might itself would have started from the Big bang These points are actually favouring Atheism , i just wanted explanation and answer to these points ... Just wanted myself to be sure that the Universe has not made itself ,but there is a God (Allah) who have made it ,
