[ WP ] Write a story that ends with a phrase `` I was wrong '' and this phrase explains everything

We watched the ships land with hope in our hearts. The priests sang out, `` Our saviors are finally here''. The scholars proclaimed that a new age was about to begin- an age of peace and understanding. The poor ran out to the sea with simple gifts of flowers and fruit. Some went so far as to leap into the ocean and swim out to greet the gods. Their white sails seemed to reach into the clouds, their pale skin confirmed their divinity. 
 We welcomed them into our lands, and at first they seemed pleased by the gifts and adulation that we heaped upon them. We, in turn, saw their approval as proof that the signs were correct- the gods had indeed come. But these were not gods, they were men; and they had the same desires, the same faults, the same problems, that make even the best of men turn into beasts. 
 I do n't know what caused the problem, perhaps it was always meant to be. They raised their weapons of destruction and released their terrible fury upon those devoted to their glory. The air itself seemed to erupt in thunder, smoke bellowed out like the putrid breath of a thousand volcanos. We could smell the acrid sulfur all around us as the screaming began. 
 Our warriors were cut down, our weapons of stone and wood held no threat to these mighty beings from beyond the sea. Those who could run made their way into the safety of the forest. Everyone else was killed where they stood. We thought they came to save us. We thought they were gods. We thought Quetzaquatal had returned. we were wrong.
