Amazing,
It this fascinating to imagine that earth is not a planet where life stars on its own independently. But some other advanced race on other planets has used the earth as their superlab to study evolution. They always keep watch on us, never interrupt other day-to-day activities, but always guide us to overcome natural calamities. They also save us from alien attacks.

With time human species get developed as superior on earth, started to pollute the earth, exploit natural resources at a high rate. But they do not put their hand. But when humans started to make nuclear weapons, almost every country has its own large storage of nuclear weapons. They become alert and diffuse all weapons saving all earth living things.
Also, give the message that keeps this earth-friendly to live.
The author has nicely arranged all periods of earth appropriately.
