Technically it was humanity who basically made the Flood XD
But in all seriousness, we don't know who or what made the canisters of dust that the Flood evolved from, it could have been made by the Precursors, it could be poop from a Chickenpede, we really don't know where it came from, but I really don't think that it was the Precursors.
The matter of the Prisoner being related in some way to the Gravemind, I think is a big definite, the two are most certainly connected and the Prisoner either becomes the Gravemind or is absorbed by a less evolved Flood intelligence that becomes the Gravemind. But yeah, it's pretty certain that the two are linked.
