Every creature on this planet that is deemed multicellular, is a symbiote of some sort. The short definition of symbiote, is organisms that coexist for mutual advantage.
In our case, every different type of cell; bone, blood, skin, brain etc... are acting symbiotically, to make a whole: a human.
Put succinctly: we could not be a complex organism, as we are, without symbiosys. We would just be giant amoebas

Why? Probably just because it worked out that way.
We are host organisms to both bacteria and mitochondria, which both have different genetic codes than us. There may be others as well, I'm no biologist.
What I do know is that bacteria greatly help us in our digestive processes by breaking down food into more managable substances. Too few bugs in your intestines would make you almost as sick as the wrong kind of bug!
Also, mitochondria, incredibly tiny creatures that live in every single living cell in our bodies do a similar task, breaking down substances in our blood into fuel for our cells.

It's convenient for us as well as the little critters living inside of us. The microbes that live in us help us with digestion and possibly a few other things, not quite sure what...but I'm leaving that open.

As we act as a host, we get plenty of advantages like in digestion, cleaning.
