Not "life as we know it". Oxygen is poisonous, as all Scuba divers know; below about 30 feet depth, pure oxygen will kill you, and a few people react badly to oxygen in normal pressures.
And without nitrogen and carbon dioxide, plants would be unable to live.
What else can I help you with?
Could life exist on Earth if the air contained only oxygen?
No. The oxygen would be too concentrated and we would die.
Why air is needed by livingthings?
It's not the air that's needed - it's the oxygen ! Life on Earth developed by relying on oxygen to sustain it. The 'air' could be made up of totally different components - so long as it contained about 20% oxygen.
Could life as we know it exist on earth if air contained-only oxygen?
Simplistically, if our atmosphere contained only oxygen, then any tiny spark or flame would be enough to set anything flammable ablaze. More realistically, plants need carbon dioxide, and nitrogen is needed to make proteins, an essential part of all life as we know it.

Is oxygen manmade?
No. Earth's oxygen is provided by plants. Humans need oxygen to live, so we could not have been there before there was oxygen, so we could not have made the oxygen.

How does oxygen make life sutable on earth?
Oxygen makes it human capable of breathing in earth that's why when there is oxygen, there is life.
Effects of no oxygen on earth?
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
Why does oxygen occur naturally?
Oxygen occurs naturally because it is produced through various biological and physical processes. It is one of the most abundant elements on Earth, being released during photosynthesis by plants and algae, as well as being a byproduct of the respiration of living organisms. Oxygen is also present in the atmosphere due to its interactions with sunlight and ultraviolet radiation.
