Samaalic Era
QurboExit
all humans lived in that region, no one really know, Allah does tell us the mountain the ship landed on is called judy -juuudiii, maybe it was iraq, who knows only God, but we know of all humans only 70-80 or so believed and survived
and only allah knows, dont concern yourself with this or that, just focus on salat and the fard actions required,
You are right sxb. This is just trying to piece together history of mankind and lineages which is a worldly knowledge although it is useless in the hereafter. Knowledge of Lineages and tracing iconic events from the Qur'an is something i find fascinating
