Sometimes I think-No Holocaust could have ruined the entire Civilization of the world earlier and shall never in future.The oldest proof of the civilization of prehistoric eras available as per archaeological department or any other means implies that or confirm that non of any earlier civilizations of ancient days were more developed than us scientifically or in any other aspect more than today's.Phone,mobile phones,TV,RCC Buildings,bridges ,electricity,vehicles,washing machine, roads along with more civilized people who love each others, irrespective of places,castes and countries were never existing earlier.Medical science is also very very developed than earlier or ancient days.Is that God is also researching and modifying his earlier researches along with us and trying to form a better and better livable earth/ situation for us?And the experiments he had done earlier has been abandoned by him as it were of old technologies unfit for today.
