I think the forerunner/human time travel with the MC would be quite valid and that the forerunner maybe responsible for the creation of the flood, if the forerunners were in a conflict with the flood which they came across, the war must have lasted a long time,as to study,plan and then build all the halo structures and the ark this would have taken an immense amount of time and resources even for an advanced race but this is guessing as i dont know the average build time of a halo structure let alone the placing of it,staffing,quarantine of the flood,digging into the earth planting the ark or building earth around the ark,so either the forerunner were aware of the threat and built the halo's early (possible time travel interference with the MC warning the forerunner?) or built the halo's in a prolonged war with the flood
