except that we see in the manga that most humans have not know about ghouls for that long, the higher ups hiding their existence from the comum folk till some years ago, and even now most doubt their existence(Fura in JACK didn't know what ghouls were, and kaneki in the start knew they existed but sort of doubted it). So, or they were hidden really well for centuries, which i doubt, or they are a new specie that mutated from humans (since humans also have rc cells) a round 100 years ago(around the time of the creation of the CCG) or they were created around the same time from some experiment
