It depends on the universe since in some universes they're programs created to fight each other and survive while iterating on themselves and being culled by the D-Reaper (Tamers) while in others they just exist (Adventure and 02), and in others they exist and humans only found out about their existence through happenstance (CS and HM). They live on certain major servers that determine if the Digimon can live or need to be eradicated with guardian protectors of the server (Royal Knights) or other stuff like the Olympos XII. There's no real set way they work and to my understanding sometimes the servers aren't even man-made.

In general the humans find out they exist either by them literally coming into the human world because of various means like Demon in Adventure 02, Vampmon in Adventure, the incursions due to Culumon leaving it in Tamers, or because of Eaters in CS and HM.
