If you want buy car, you will find car that make by those trusted car automaker like bimmer and merc. So the car has its own maker or someone that create the car. Same goes to your daily need such a watch, iphone, tv,radio,shoes,shirt, internet, house and etc all have their own creator or someone that make those item. But why you deny that you are also have your own creator that is god.for muslim it call Allah.how come those beautiful forest,ocean,mountain and those complex animal like tiger,lion, cheetah have not create by someone powerful. Not to mention those hot sun,moon and star.what make you think all those amazing thing around you those not have their creator and Terjadi semula jadi. If someone say that their house is semulajadi, you must think he crazy right?

As a Muslim,I definitely believe that God is One and that is Allah.He (God) is not a creation but he is the one that create everything and life.Mankind not been given privilege in their brain to find how God been created and where he is.He is the one who guide people that he wants to the right path.I believe in Injil (Prophet Jesus) but not as God as Christian faithful believe.

“Imam Fakhrudien Raazi (Rahmatullahi ‘alayh) was a brilliant and gifted Scholar. Yet on his death bed, shaytaan came to him with strong arguments that Allah (Jalla Jalaaluhu) does not exist. The Imam presented one hundred proofs of Allah Ta’ala’s existence. His shaytaan was such a Scholar, who broke every single proof of his. He then saw his Sheikh in a vision who said: ‘Say: I believe in Allah without any proof!’
