according to my religion, Islam, there are things we can get by our logic, our brain. one of them is this question. if you keep asking who created this, this, and this, the question will be never end. so this is the answer of your question by Islam :
Abu Hurayrah (may Allaah be pleased with him) said: the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “People will keep on asking questions until someone will say, ‘Allaah created the universe, but who created Allaah?’ Whoever encounters anything like that, let him say, ‘Amantu Billaah (I believe in Allaah).’”
The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The Shaytaan will come to one of you and say, ‘Who created the heaven? Who created the earth?’ He will say, ‘Allaah’” – then he mentioned something similar (to the previous report), and added, “And His Messengers.” [i.e., amantu Billaah wa Rusulihi = I believe in Allaah and His Messengers]
The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The Shaytaan will come to one of you and say, ‘Who created such and such?’ until he says to him, ‘Who created your Lord?’ When it reaches that stage, let him seek refuge with Allaah [say A’oodhu Billaahi min ash-shaytaan ir-rajeem = I seek refuge with Allaah from the accursed Shaytaan] and stop thinking about it.”
The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The Shaytaan will come to a person and say, ‘Who created such and such…’” and he narrated the whole report. (Imaam Muslim, 134).
He (peace and blessings of Allaah be upon him) said: “O Allaah, You are the First and there is nothing before You; O Allaah, You are the Last and there is nothing after You.” (Narrated by Muslim, 2713)
He (peace and blessings of Allaah be upon him) said: “Allaah existed when there was nothing apart from Him.” According to another report: “There was nothing before Him.” (Narrated by al-Bukhaari; the first report 3020; the second report 6982).
So muslims are not interested in philosophical arguments on the creation of Allah, rather they see these questions as the tricks and deceptions of the shaytaan. Muslims belief that Allah created mankind and installed in their inherent nature (fitrah) his belief as is mentioned in Quran:
So set you (O Muhammad SAW) your face towards the religion of pure Islâmic Monotheism Hanifa (worship none but Allâh Alone) Allâh's Fitrah (i.e. Allâh's Islâmic Monotheism), with which He has created mankind . No change let there be in Khalqillâh (i.e. the Religion of Allâh Islâmic Monotheism), that is the straight religion, but most of men know not. [Tafsir AtTabarî, Vol 21, Page 41] (Ar-Rum 30:30)
it's kind of test, we choose to believe in Qur'an (Allah, the creator, said) and Prophet Muhammad (the most hinest and perfect man ever) or believe in our logil that isn't perfect.
