ELI5: When there is a fly in my room and it is continuously flying around in the same pattern, what is it trying to achieve?

It's annoying but I feel sorry for the little guy. He seems to know no better.

Flies have, by human standards, virtually no brain. They are better understood as being like a tiny machine rather than a tiny thinker. So they are not "trying to achieve" anything, and are unaware of what they are doing.

Flies respond primarily to smells, and secondly to rather basic images. They seek things that smell like food, and seek to avoid getting swatted or eaten.
