The question presupposes that there has to be a purpose to life. This is a common miss-understanding, obviously creationists desperately try to attribute every species to a special act of creation by an intelligent designer, so have to come up with some 'point', however contrived and silly, for everything (Some of the responses to Darwin's challenge about the carnivorous wasps, for example, were downright daft. And I recall Steven Gould writing about one Victorian theologist who claimed that wood-boring worms existed to help the economy of Scandinavia and provide employment in Holland!)
But even some atheists and agnostics miss-understand the concept of evolution and natural selection, thinking that there has to be some drive, some direction to it, as if individual species and even individual creatures have some kind of ultimate goal, something they are reaching for. This just isn't so - NS is indeed a 'blind watchmaker', who doesn't even know what a watch is!
It is true that organisms fill ecological niches, sometimes with amazing efficiency, but that is not the same as saying that this is their 'point'
If rats and flies, or you and me, can be said to have a point at all, it is the perpetuation of our own genes into posterity. Nothing more. Any apparent altruistic, co-operative or beneficial effects are co-incidental.

Organisms don't have a purpose, they simply exist as a result of natural selection.
You might just as well aks what the purpose is of a rock on the moon. Your question makes no sense.

All organisms evolve to eat/degrade some substrate wether it be decaying matter, specific elements or other organisms. It's the same as there are organisms which are able to survive in any environment. If there is a niche, there is a way.
Rats and flys exist as they are best suited to live where they live and eat what they do, they have adapted to their environment and food availability to become what they are today

Flies are decomposers, and if there were none the world would be, like whatsisname said, and huge pile of decaying crap. rats are scavengers, and do basically the same thing as flies, but i'm not quite sure about that one.

The purpose of life is to live, experience life, and reproduce.
Everything that is alive is able to do that. Flies, rats, mosquitoes, cockroaches and ants all do that.
;-D As long as they can do that, they will live, and we will be bugged by them.

Their purpose is to exist. Like most, if not all, scavengers, they serve to keep the Earth relatively clean.

If there were no flies there would be dead decaying crap all over the place. Rats are just turds with fur.

If there were no rats only other recourse would be stools, as for the second....well it would be very much more difficult to pee.
