There is really no room for anyone's "opinion" on what killed the dinosaurs. There is a consensus based on the evidence we have found.

The most widely accepted explanation for the extinction of the dinosaurs is the Chicxulub asteroid that impacted the Yucatan Peninsula 65 million years ago. It would have caused a great deal of climate change in very little time and disrupted the food chain.

That was likely combined with a spike in volcanic activity that was probably already poisoning the atmosphere before the asteroid came. Anything that could not cope, including the dinosaurs, went extinct.

Not only the dinosaurs died, many marine and terrestrial species died out too.

But if you really want to know my opinion, I believe aliens visited the Earth, saw those ugly monsters, and decided to just annihilate them on the spot.
