The ability to use oxygen in a biological organism evolved long before humans. That does not answer the question, but life on earth would have had to evolve in a totally different way to use nitrogen. Oxygen is a much more reactive element with other elements releasing energy when it reacts, nitrogen is practically an inert element requiring large amounts of energy be added to make it react. Oxygen is so reactive that it was a poison to early living things when the cyanobacteria started releasing it into the atmosphere about 3 billion years ago. Remaining living things to which oxygen is a poison are called anaerobic organisms. The living things that depend on oxygen are called aerobic organisms. Even aerobic organisms that depend on oxygen find its extreme reactivity toxic in many ways and had to evolve complex ways to counter this toxicity, but the tradeoff of much more available energy than anaerobes can get, makes it worth the extra cost of countering the toxicity.
The creationist answer to your question is simply that is just the way God created them. Don't argue, he's God and knows what is best.

Human beings did not evolve to breathe nitrogen because nitrogen is an inert gas and does not participate in metabolic processes necessary for sustaining life. Oxygen is essential for cellular respiration, which is why humans evolved to breathe oxygen instead of nitrogen. Nitrogen makes up a large portion of the Earth's atmosphere, but it is not used by our bodies for energy production.

Did humans evolve from chimps grasshopper evolve from earthworms hydra evolve from sponges?
Humans did not evolve from chimpanzees, but rather share a common ancestor with them. Grasshoppers and earthworms are different species with their own evolutionary histories, and similarly, hydras and sponges are distinct species that evolved separately. Each species has its own unique evolutionary path shaped by natural selection and genetic adaptations.
How did human settlement evolve?
Human settlement evolved over time in response to various factors such as availability of resources, climate, population growth, and technological advancements. Early humans were nomadic, moving from place to place in search of food and shelter. As agriculture developed, people began to settle in permanent villages and towns. Urbanization occurred as societies grew more complex and trade networks expanded, leading to the establishment of cities. Today, human settlement continues to evolve with urbanization, technology, and globalization shaping the way we live.
What is does anthropology say about bring human?
Anthropology studies what it means to be human by examining the biological, social, and cultural aspects of human populations. It explores human evolution, variation, and behavior across different societies and time periods to understand the complexities of human existence.
How long ago did the modern human species evolve?
The modern human species, Homo sapiens, is estimated to have evolved around 300,000 years ago in Africa.
What is an antropolohist?
An anthropologist is a social scientist who studies the cultural behaviors, beliefs, and practices of human societies. They often conduct fieldwork to understand and document how different cultures function and evolve over time.
How does nitrogen help us?
nitogen helps human to breath.....
What are the consequences if nitrogen gas is absent from Earth's atmosphere?
ancomfortable breathy systerm because when you breath oxygen in you body scienty say that human can breath 1% of nitrogen inorder to newtrories
Where do human get nitrogen in their diet?
Humans get nitrogen in their diet by eating plants (herbs etc) Hope this helps :)
Is nitrogen harmful to the human body?
If we were to inhale pure nitrogen, we would obviously die from lack of oxygen. Otherwise no, you have to understand that 70% of every breath you take is nitrogen
Why human not die breathing mostly nitrogen in atmosphere?
The air we all breath is over 70% nitrogen and although we do not need this it is not toxic to us, most of the rest of the air we breath is the oxygen we need to remain alive.
Is nitrogen important for survival?
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.
What is the primary component of an exhaled breath?
Nitrogen, there is 78% of nitrogen exhaled Nitrogen, there is 78% of nitrogen exhaled
Is nitrogen air?
Nitrogen makes up about ~80% of the air we breath in.
Is nitrogen in the air harmful?
Around 80% of air we breath is nitrogen.
When do you use nitrogen?
Take a breath.
Why nitrogen is used as disinfectant?
Nitrogen is NOT a disinfectant. The air we breath is 80% Nitrogen, if Nitrogen were a disinfectant there would be no life on Earth!
Bacteria changes nitrates in what way?
Bacteria breath in nitrogen and breath out nitrate/
