There were probably numerous eye witnesses of the Burckle ocean impact. Most of them didn't live to tell about it. I find it suprising that only one Sumerian version was found. Only one person explaining an event doesn't paint a full picture. A crime scene needs multiple witnesses to make a good case. I bet at least one individual saw the comet before the tsunami hit land.

Some 19th century writer figured out the Nochian deluge was caused by a comet. The main character in the novel says.

"Soon after midnight I was awaken by a sound in the air, like a shriek or wail passing over the valley. Afterward came short sudden gusts, succeeded by hollow intervals of intense calm. Beneath, a sullen far off roar caused the earth to tremble. As faint dawn glimmered in the east a heavy blast swirled down from the north which shook our building. In a few moments came a hot wind from the opposite direction. The air was filled with dust and at the same time an unusual dampness and a saline odor. Entirely across the entrance of the valley, crowding the very mountain tops, appeared a mighty wall, tottering, crashing, falling, pressed forward by some invisible power. Upon its awful front, in confusion which dazed the sight, were borne trees and timber, fragments of buildings, earth, rocks and mutilated bodies of animals and creatures of the sea; but most dreadful of all were the the ghastly corpses of dead men and women."

Seola, 1878, Mrs. J.G. Smith
