I believe common wisdom speculates the one off the Yucatan was the crater that did in the critters some 65 million years ago. But recent evidence indicates there might have been more afoot than that single meteor to cause dino's demise. Check this out:
"Far more than a meteor killed dinos
There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, according to a paleontologist who says multiple meteor impacts, massive volcanism in India, and climate changes culminated in the end of the Cretaceous Period.
The Chicxulub impact may, in fact, have been the lesser and earlier of a series of meteors and volcanic eruptions that pounded life on Earth for more than 500,000 years, say Princeton University paleontologist Gerta Keller and her collaborators Thierry Adatte from the University of Neuchatel, Switzerland, and Zsolt Berner and Doris Stueben from Karlsruhe University in Germany. A final, much larger and still unidentified impact 65.5 million years ago appears to have been the last straw, exterminating two thirds of all species in one of the largest mass extinction events in the history of life. It's that impact – not Chicxulub – which left the famous extraterrestrial iridium layer found in rocks worldwide that marks the impact that finally ended the Age of Reptiles. " [See source.]

Well.... since there were no humans when dinosaurs walked the earth, that's hard to answer... However, it does not have to be a meteor that killed the dinosaurs - though it does fit with the global KT boundary iridium rich clay layer. However, a commet is frozen methane gas... A big comet (like Haley) hitting our atmosphere would wipe out everything over the size of a finch on the surface of the earth.

It may help to consider that no meteorites, nor any natural phenomenon ever happened "so" that humankind could do anything.
This would suggest an aim or meaning to natural events toward the goal of human existance, and appart from being an incorrect assumption, this sounds too much like many fruitcake religions in its premise.
Otherwsie I think your question has already been answered..
