well then lets see you make a thread saying "does god exist" and see how many people here agree with you
God is flexible. Punishments are meted out sometimes based on the ability or knowledge of AN INDIVIDUAL.
But just think. If there is say 4 billion people who will live in the earth throughout eternity and you need to meet each one, say even have an intimate relationship with each one every other year, then it would take 8 billion years to complete that cycle at the end of which time you would have had SEX WITH EVERY OTHER HUMAN on the planet and you could say you know them.
The evil was the myth of Ham(?) that Africans were cursed by God and man must mete out the punishment. Literature developed that they were NOT FULLY HUMAN but more akin to wild animals. This was the key difference between the Atlantic slave trade and slavery in Jesus' time.
