»How come architect says and shows Neo the Ones before Neo«

problem is he shows many Neos,and says that there were many before him and they all made their choise.Merovingian also sad
something like 'others before you weren't so rude',how come is that,who were the others,why no one in the real world had ever heard about them?
the war is only 100 years old ( thats what Morpheus sad in the caves before the party ),how can there be many Ones when there is no mention of them in Zion,or real world?
it's impossible and I haven't seen any comment about it.
