The one true God walked through the scorched ruins of civilization.
He thought.
In the beginning, they had been his greatest creations...in the end, his most devastating failure.
He smiled, but it was a smile filled with sadness and irony.

Say what you will about humanity, he thought, but they never did anything important half-assed. An individual may procrastinate or slack off, but look what they had done over time, how they had affected their world.
He now stood in the center of what used to be one of their greatest achievements...a sprawling metropolis, once populated by millions of people. People of every race, religion, and creed had lived here...some laughed, some loved, some screamed or cried or swore or prayed or played, but all LIVED, for at least a little while.
Now a few charred chunks of concrete and steel littered the otherwise barren landscape, one final clue that life had once existed on earth.
The fall had been coming for a long time, he knew...hardly sooner had they learned how to live then they learned how to kill. Before long they had become curious about their origins, the source of their existence. Stories began to spread among them, many close to the truth, but none hitting on the mark.

However, many of them began to hold these myths as truths, and stories became religions. This was the beginning of the end.
