i know the bible doesn't tell us everything after all it was just compiled by man, and i don't blame God for the missing pieces though. neither i rest my case on them, who knows someone might find them sooner or later..
the only thing that makes the bible passages are accepted as it is is no one has yet found anything that connects with it(though i'm not telling that the bible is not credible enough what i mean is perhaps there must be other pieces that would fill to some missing informations)..
