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.

Does Earth have the industrial and technological capacity to launch a self contained lifeship that could travel to another star?
No. The resources may perhaps exist that could be utilized to develop that ability, but it doesn't exist now.

Is oxygen found outside earths atmosphere?
Yes. Earth's atmosphere is about 21% oxygen. Without it, the vast majority of life we see, including humans, could not exist.
On earth oxygen usually exist as what?
Oxygen usually exists as a diatomic molecule, O2, in the Earth's atmosphere.
What condition had to be in place on earth for water to exist here?
For water to exist on Earth, the temperature needed to be within a range where it could exist in liquid form, between 0-100 degrees Celsius. Additionally, Earth's atmosphere needed to have the right combination of gases, like oxygen and nitrogen, to create the conditions necessary for water to form and remain liquid.
How is oxygen important to society?
nothing on earth would exist
Reason why life can exist on earth?
because there an oxygen, water, and food
What would happen if oxygen did not exist?
Life on Earth, or at least most of it, would not exist without free oxygen. It is possible that some other form of life, based on another element, could exist in a non-oxygen environment. But none has been discovered as of now.
