how much more do you mean?

Yes, and it did. Now it is supporting life with less O2. There must be a balance, which is why deforestation, and large human populations could eventually deplete the oxygen, and kill us. And with too much oxygen, the trees would die. One can not live without the other. It would be better to have more oxygen than we do now, but too much and the atmosphere would become very combustible.

Apparently so, since it's only pure oxygen that can damage us. Even a higher level of oxygen wouldn't be harmful, we breathe in a mixture of oxygen-nitrogen.

Yes.
Geological evidence has suggested varying levels of oxygen, nitrogen, and carbon dioxide over the course of earth's evolution.

yes, it used to be 32% in past.
Oxygen found in Amber shows that the oxygen level was higher in the past

Yes-- but I'm sure there's a limit.
There has to be some C02 in the air for plants to live.

Many scientist think it used to be about double what it is now, and the pressure may have been higher too.
