As the sun set on the final day of humanity, a lone figure sat on the edge of a cliff, staring out at the vast expanse of the empty world. The sky was a deep, inky black, punctuated only by the faint twinkle of distant stars.
"All the world's a stage, and all the men and women merely players," the man thought to himself, quoting the philosopher William Shakespeare. "They have their exits and their entrances, and one man in his time plays many parts."
The figure was a man, though it was difficult to tell from his appearance alone. His skin was ashen and grey, his eyes sunken and hollow. He was thin and gaunt, his clothes hanging from his frame like rags on a scarecrow.
"To be or not to be, that is the question," he thought, quoting Shakespeare once again. "Whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles and by opposing end them."
As he sat there, staring out at the desolate landscape, he couldn't help but feel a sense of deep, overwhelming despair. He thought about the countless generations of humanity that had come before him, and how they had all ultimately ended up in the same place.
"All that is solid melts into air," he thought, recalling the words of the philosopher Karl Marx. "All that is holy is profaned, and man is at last compelled to face with sober senses his real conditions of life, and his relations with his kind."
He thought about the great civilizations that had risen and fallen, the incredible achievements that humanity had made, and the terrible atrocities that they had committed. He thought about the endless wars and conflicts that had ravaged the world, and the countless lives that had been lost in the pursuit of power and glory.
"We have become great because we have been forced to be great," he thought, recalling the words of the philosopher Friedrich Nietzsche. "But one day, all of this will come crashing down, and we will be left with nothing but the ashes of our own destruction."
In the end, it had all been for nothing. The man knew that humanity was doomed, and that their legacy would be one of destruction and destruction alone.
As he sat there, lost in thought, a single tear rolled down his cheek. He knew that there was no hope for him, or for any of the other survivors.
"The only true wisdom is in knowing you know nothing," he thought, quoting the philosopher Socrates. "And in the end, all that we are is dust in the wind."
In the end, they were all just fleeting, inconsequential specks of dust in the great, vast void of the universe. And as the sun disappeared below the horizon, the man knew that this was the final, eternal twilight of humanity.
