We have to study world history
by which we can realize the future of the world.
Nature has acquired something which left a history and continuing
with an aim.
All the organisms are part of nature and so,
to find the aim of our life, we have to study history. The written world
histories are almost political only, which itself is baseless. There
is a prolonged history for universe, geographical nature, Ecosystems
biodiversity and its sub-histories. World history for the last five
thousand years is founded on Bible history.
The present events in the world are only remainder of the past.
Without a history and aim there is no meaning for human life.
