None, Noah was perfect in his generations. Eight Adamic souls were on the ark. The bible is the story of Adam's family and those in close contact with them, and so Noah's ark was the vehicle to save Noah's family. God may have had other vehicles for other peoples. But just as the bible doesn't give Chinese history for instance, it doesn't specify how the other people's were saved.
Since the crucifixion all that accept Christ are of Abraham now.
Whatever THAT is supposed to mean.
Just how 'perfect' was he?
"Be ye therefore perfect..."
Like comets?
“God may have had other vehicles for other peoples.”
No, there were 8 people on the ark, and only 8 souls were saved from the flood, so there couldn’t have been other vessels:
“18 For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
19 By which also he went and preached unto the spirits in prison;
20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.” 1 Peter 3:18-20
