Aliens May Destroy Humanity to Protect Other Civilizations, Say NASA Scientists.

“Is Contact with Extraterrestrials a Benefit or Concern for Humanity? A Scenario Analysis” is an article published by NASA scientists. In the text, they argue that the growing emission of greenhouse gases can show the ETs that we are an expanding threat.
According to them, aliens may be following changes in the Earth’s atmosphere as an indication that our civilization is growing without limits and may take drastic actions so that we do not become a serious threat.
This is one of several scenarios described by scientists, who despite believing it to be unlikely, believe it is important to prepare humanity for contact. They divide the hypotheses into three categories: beneficial, neutral, and alarming.
The good ones range from the mere detection of extraterrestrial intelligence, for example, by intercepting alien communication, to contacting cooperative organizations that can help advance our knowledge and solve global problems such as hunger, poverty and disease.
Another good result would be to defeat a group of aggressive ETs or even be saved by another group of aliens. In this case, humans, in addition to leaving with the highest morale for the victory, could still know extraterrestrial technology.
The most unpleasant results would arise if they caused harm to humanity, even by accident. ETs could come to eat, enslave or attack us, but people could still suffer from alien diseases. They might even want to carry out catastrophic experiments that could wipe out a part of the galaxy.
To bolster humanity’s chances of survival, the researchers urge caution in sending signals into space, and in particular, they warn against spreading information about our biological make-up, which could be used to manufacture weapons. Instead, any contact with ETs should be limited to mathematical discourse “until we have a better idea of ​​the type of ET we’re dealing with,” the authors said.
Extraterrestrials may be wary of civilizations that expand too quickly, as these may be prone to destroying the lives of others as they grow, just as humans drove species on Earth to extinction. In the most extreme scenario, aliens may choose to destroy humanity in order to protect other civilizations.
Therefore, they warn of the decrease in the emission of greenhouse gases, which alter the Earth’s atmosphere, which can be seen from space, and would indicate to extraterrestrials that our civilization is expanding. If we already have enough reasons to avoid the emission of gases to preserve life on the planet, we just won one more!
