Air is the most important thing for human survival. If we don't get air and oxygen for a few minutes, we will die. Today, it has been proven that the air on Earth is completely compressed in the areas near the Earth and is ready for human breathing, but the higher we move, the thinner the air becomes and the less oxygen it contains. If we move a few kilometers away from the Earth, breathing will become more and more difficult for us. If we continue to move forward, the lack of oxygen and shortness of breath will cause our lungs to contract and we will faint.
This scientific fact has been discovered in recent centuries, while God clearly states it in the Quran:
الانعام
فَمَن يُرِدِ ٱللَّهُ أَن يَهۡدِيَهُۥ يَشۡرَحۡ صَدۡرَهُۥ لِلۡإِسۡلَٰمِۖ وَمَن يُرِدۡ أَن يُضِلَّهُۥ يَجۡعَلۡ صَدۡرَهُۥ ضَيِّقًا حَرَجٗا كَأَنَّمَا يَصَّعَّدُ فِي ٱلسَّمَآءِۚ كَذَٰلِكَ يَجۡعَلُ ٱللَّهُ ٱلرِّجۡسَ عَلَى ٱلَّذِينَ لَا يُؤۡمِنُونَ (125)

Whoever Allah wills to guide, He opens his heart to Islam; and whoever He wills to lead astray, He makes his heart tight and constricted, as if he were climbing up into the sky. This is how Allah punishes those who do not believe.​​​​​​​
