What have we learned?

[Kurk]

If Iris is indeed finished, what overall has it revealed to us about the halo universe?

- The Flood are extra-galactic in origin

[SpartanSeraph]

-humans and forerunner are separate species
-forerunner intended to keep flood specimens for study

[Mjonir]

- When Floods become important in number, a Gravemind is created
- There was a GRavemind before, at the Forerunners time
- He spoke to them
- Forerunners created the Earth

[Van Helsing]

Forerunners created Earth??

[MulletedOne]

- Forerunners created the Earth

Erm, the Forerunners found Earth late in their fight, built the Ark to preserve the life there for study after the whole Flood problem was taken care of, but mysteriously haven't been heard from since.

[ProfessorHojo05]

-The Forerunners were surprised by something that they found on earth which prompted them to protect it.

-We have clues as to how the halo arrays computer systems processed as they fired.

-We have clues as to how the halo arrays computer systems processed as they fired.

(I keep forgetting about that one!)
-The Halo firing 100,000 years ago was not an accident, but a conscious choice made as a last resort.

[Xastabus]

-Humans are the "Reclaimers"

[sharpsniper99]

the forunners discovered that humans held the way to defeat the flood, but "ironically" put in place the halo system before discovering this

the forunners discovered that humans held the way to defeat the flood, but "ironically" put in place the halo system before discovering this

Which begs the question, "Why'd they still fire it?" Or was the Flood "epidemic" past the point of recovering from?
