There was no standard reference when the new era of a civilized mankind began. The founding fathers had been forced to start a new world order and as time passed by, many references appear.

If the ruler of this world really believes that earth's history repeats itself again and again, then I understand why the truth about prehuman civilizations are kept secret so tight.

This civilization is the impact of the world's consumption behavior.

There are some people who desperately want to change the world. I wonder if it could be measured, because the world is already in a state of continuous change since the beginning of time. Or maybe they just want their names etched nicely in the history of mankind.

Science is a trigger of changes of civilization.
Religion is the failsafe of science performance.

Parents restrict their children accessing weird sites on the internet. Same reason, the ruler of this world restricts public accessing the sites of alien civilization everywhere.
