many were saved

for probably more than 123 years 

all righteous humans were genetically modified 

so that they only gave birth to righteous children 

that were genetically designed to be righteous 

and that have increased survivability 

and the rest of all humans died in heart diseases, cancer diseases, hereditary diseases, pathogen diseases, conflicts and disasters 

which led to collapse of countries 

and if all righteous humans were upgraded to cyborgs in the 1980's 

so that they only gave birth to cyborg children 

that were cybernetically designed to be righteous 

and that have increased survivability 

and if the rest of all humans died in heart diseases, cancer diseases, hereditary diseases, pathogen diseases, conflicts and disasters 

and were turned into braindead meat puppets 

that avoided collapse of countries 

then that would explain a lot
