This is because of incandescent reaction.The filament would burn up immediately in the presence of oxygen.Incandescent reaction takes place without oxygen(anaerobic).The tungsten used for the filament would expire immediately were it introduced to oxygen turning the incandescent reaction into a brief flame.End of filament.
The gas most commonly used is argon gas.The same gas used as a purge during mig welding.
The filament would oxidize not oxidate.Oxidate isn't even a word relavent to this question.It's spelling suggests oxygen(oxi) and acid(ate).The ate suffix in chemistry always means an acid or acidic vehicle(way to transdermally deliver a drug).

If air were still present inside the bulb, the filament in the bulb would quickly oxidate and burn out. The air is removed to prevent this.
