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.

Did humans evolve from chimps grasshopper evolve from earthworms hydra evolve from sponges?

Human Beings evolved from the mud worm (as did many other species). Scientists recently discovered that before today's Human Being, there were several species of humans that existed in Africa. References - PBS Documentary, Becoming Human: Nova (Episodes 1-3) Note: There were no human beings or chimps 4 billion years ago because at that time, the earth was only 600 million years old. Despite what some believe, Humans did not exist when dinosaurs existed.


What is does anthropology say about bring human?

Anthropologists look at 5 main points: What is a human being? How are humans different from other living creatures? Where did we come from? How did we originate and evolve? How to humans work and reshape the world? How do we order our lives with other human beings? How do humans deal with the unknown

Did humans evolve from a star?

No. Humans are not made from stars. However, every element in the human body except hydrogen and perhaps lithium came from an exploding star. The human body contains carbon, nitrogen, oxygen, iron, chlorine, sulphur, and a number of other elements, all made in stars. All became available for other uses when the stars exploded.

Why human not die breathing mostly nitrogen in atmosphere?

Humans breathe a mixture of gases in air, not just nitrogen. Nitrogen itself is not harmful to humans in normal concentrations found in the atmosphere. However, breathing pure nitrogen can displace oxygen in the lungs and lead to asphyxiation.
