Hawking: Stop trying to communicate with aliens.

There is an arid planet whose creatures are searching every day for a planet in the universe that might be suitable for migration.

Due to their extreme lack of water resources. They have therefore developed organs that can store water.

One day, two creatures tasked with observing the stars discover a planet full of water. They launch their spacecraft to the planet to make a preliminary exploration.

They found that the planet's soil was so rich in water and minerals that creatures could get enough water and nutrients just by eating it.

So they sent out a signal to their original planet, calling for their companions to migrate to this fantasy planet.

But because they can never forget the experience of living with a lack of resources. As a result, they always overeat.

Even a planet with abundant resources cannot afford to over-consume over a long period of time.

Their over-exploitation eventually led to the destruction of the planet and they did not escape extinction.
