[quote][b]Posted by:[/b] SIFU8 Though I admit I haven't read the newest book from what I understand the flood was discovered by humans by accident. It's possible that the precursors created it or perhaps discovered it but the forerunners I believe merely examined it to understand it more, mainly to find a way to combat it more effectively. The ships that the flood spores where found on where of unknown origin which could mean precursor or possibly something else.[/quote] All of that is a misconception, the flood did not form until humans ate the pheru that had abnormal growths if they didn't do that then the flood wouldn't have manifested.
