God created the atmosphere on the second day of creation.
Genesis 1:6-8 And God said, "Let there be an expanse between the waters to separate water from water." So God made the expanse and separated the water under the expanse from the water above it. And it was so. God called the expanse "sky." And there was evening, and there was morning—the second day.
The earth is the only planet in our solar system to have oxygen in its atmosphere.
Our atmosphere is 21% oxygen. It is also made up of other gases, specks of dust, and water.
The water in our atmosphere gives us our weather.
The ozone layer above the atmosphere protects us from the sun's harmful ultraviolet rays. Without the ozone layer, all living things on the earth would die in a very short time.
In the Bible, "breath" and "life" are sometimes used to mean the same thing.
Isaiah 42:5 "He who created the heavens and stretched them out...who gives breath to its people, and life to those who walk on it."
We need to praise God for everything - including the air we breathe.
Psalm 150:6 "Let everything that has breath praise the Lord!"
