Answer:

The main reason why fire needs oxygen is mostly due to the presence of carbon in the material which is burning. Carbon reacts with oxygen to create carbon dioxide, this reaction creates a lot of heat giving us what we call “fire”.

Fire has no needs, wants, or cares. Fire, aka combustion, is a rapid, energetic chemical reaction between an oxidant and something combustible. Since oxygen is a highly reactive oxidant (the term got named after oxygen) and the atmosphere is 21% oxygen, almost all fires involve oxygen reaction with something combustible. So, fires involve oxygen because vast quantities of it are available everywhere and it is very good at oxidizing things (another termed names after oxygen).

The fact that the term “oxidizing agent” exists tells us that there are other things that can do what oxygen can do, so fires can occur without the participation of oxygen.
