The Precursors invented the flood by way of a failed experiment trying to make synthetic organisms; in an attempt to kill off the Forerunners for rebelling against them. But the experiment failed and what was left of it was the corrupted organic powder. The powder was shot off into a space and found by the humans; and then the humans started experimenting on it with animals. Those animals were mutated and made the first flood spores, and then the war started. SO humanity was fighting and running while invading forerunner worlds and the forerunners were like "Y u do dis." And when they won, they were all like "Oh, das why."
