How were scientists able to come to the (pretty much universally accepted) conclusion that it was a meteor that killed the dinosaurs when no one was around to witness it?

Question

Is it even remotely possible it was something else that happened around the same time?

Answer 1

We don’t need to witness something to understand what happened. We can simply gather clues and follow those clues to their logical conclusion.

We know that 65 million years ago there were mass die offs. We also have evidence that a material called Iridium was scattered around the Earth at the same time. And we also know that Iridium is rare on earth, but common on asteroids. And we have a huge crater near Mexico that is also 65 million years old.

So we put all that evidence together and we found our answer.
