The existence of humanity is an evil blessing with the full capacity to maintain good intentions, but human nature compels us to do otherwise, in going beyond moral constraints into the depths of corruption. curiosity. The idea can be summed up most clearly in the words of Bill Bryson: “It is a disturbing thought that we may be both the crowning achievement of the living universe and its worst nightmare. » Bryson obviously sees the abilities of the human race, but nevertheless recognizes the flaws that make people far from perfect. What distinguishes humans from animals is their ability to think. The creation of nuclear weapons is the product of human intellect and is an example of its capability. But this feat has led to fears of nuclear war, which would mean the end of humanity and perhaps the Earth itself. Another example is that of the communist dictator Adolf Hitler. Hitler was a political figure who came to power after the fall of Germany. He promised the Germans the complete reconstruction of the country under his previous reign. Hitler became too hungry for power and this ultimately led to his downfall. Additionally, the development of various types of drugs (mostly intended to do good) has caused both relief and suffering around the world. A wonderful aspect of man is the ability to adapt, think and act in various circumstances and conditions. The human brain contains so much potential that 90% of it is not even accessible to humans, and yet the 10% invents, innovates, and functions on an immense scale. However, under certain circumstances and conditions, this ability can be fatal. For example, during World War II, the United States launched the Manhattan Project which aimed to create an extremely damaging bomb for the enemy, Japan. They succeeded in creating a nuclear bomb. It was a pivotal moment in history. The consequences of the bombings were so terrible that their effects are still visible today. After further research and experimentation, scientists were able to create atomic bombs that could wipe out the entire Earth at least twice. This could indeed be the “universe’s worst nightmare”. Adolf Hitler emerged into the spotlight as a man with a completely respectable goal and the antidote to poverty in Germany after the war. Hitler actually seemed to keep his word in rebuilding the country and so the Germans gave him more and more power..
