Why Allah (God) exists? Talk to an ahteist or agnostic.

Bismi-llāhi r-Raḥmāni r-Raḥīm

"In the name of God, the Most Gracious, the Most Merciful."

1. Let’s begin with reminding ourselves a simple lesson that we learned in 3d or 4th grade in school. It was about energy conservation. I believe we all remember it well:

“In physics, the law of conservation of energy states that the total energy of an isolated system remains constant — it is said to be conserved over time. In other words, this law means that energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.”

Now let’s reason. Humans are full of atoms. Which means each body possesses positive and negative energy. According to the law above energy can not dissapear or be destroyed. So how is it reasonable to say that when a body dies there is nothing left? The energy that was inside the body transformes from one form to another but it still exists just not within the organism. People call this energy “soul”. This proves that there is life after death.

How about where we got this energy from? The Creator (God) says that when HE created the first human HE breathed a soul into the man. That means that we got our energy (souls) from God’s energy.

إِذْ قَالَ رَبُّكَ لِلْمَلَٰٓئِكَةِ إِنِّى خَٰلِقٌۢ بَشَرًا مِّن طِينٍ
فَإِذَا سَوَّيْتُهُۥ وَنَفَخْتُ فِيهِ مِن رُّوحِى فَقَعُوا۟ لَهُۥ سَٰجِدِينَ
[So mention] when your Lord said to the angels, “Indeed, I am going to create a human being from clay. So when I have proportioned him and breathed into him of My spirit, then fall down to him in prostration.” 
(Qur’an 38:71-72) 

This proves that people were created by God.

That’s why many people nowadays confuse themselves saying that we are children of God. When in the reality The Almighty Creator is not a creation and does not reproduct nor was born. The Most Merciful always existed and will always exsist.

لَمْ يَلِدْ وَلَمْ يُولَدْ
He begets not, nor was He begotten.
(Quran 112:3)

• This verse means that God never gave birth and was never born. The law above states that energy is constatnt and cannot be created.

ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ لَا تَأْخُذُهُۥ سِنَةٌ وَلَا نَوْمٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ وَسِعَ كُرْسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ

Allah! There is no god except He, the Living, the Everlasting. 

[Quran 2:255]

• This verse again is proven by the law of conservation of energy stating that God never dies. Like the constant energy can never be destroyed.

The body and soul are  just a temporarely gift for us while we live on the Earth. We will have to return them one day..

2. Everything on Earth that had been created has a designer. When car was invented, there was a designer who shaped it. Anything we see or use has a specific way it looks like and someone who decided it should look this way. Be it a cup, a pen, an airplane, a hat, a plate, a cell phone etc. You name it. Now look around yourself: trees, clouds, sky, plants, rain, thunderstorm, stars,  animals.... Look at yourself: eyes, ears, mouth, head, fingers, legs, blood, brain, cells... Everything and everyone has a unique design and ideal proportion. Is it possible that everything just appeared by itself? Or was there Someone, who created and designed all of it? Won’t you reason?

3. Many say that human were created due to evolution. Others say we came to the Earth as aliens. We won’t argue today about the way mankind were created. But for sure every way had a beggining: a cell, an organism etc. The question is: “Who created the very first material?” It was The Powerful Creator that you deny.

4. If nature created itself, then show me how it can create an ant from nowhere without process of reproduction.
If you have power to create a life, create at least a fly!
