If the Flood made it to Earth, enough of them would find a way to infest humans and basically bring us to extinction. I know Bungie has said that new Halos will be in Halo 2, so that may be where we fight the Flood, or it may be on a ship or Covenant planet, but I think Earth will only be in the first part of the game.
