Are scientists right about certain animals being extinct?

Some animals, like the infamous T-Rex, are quite obviously extinct. We would know if there were giant lizard-like creatures roaming the earth, wouldn't we? But, some animals may not be extinct. There are two ways this is possible. One, when people say dinosaurs are extinct, that is not completely true. Alligators are relatives of dinosaurs. Two, just because we don't see any, doesn't mean they're not there.

How do we know?

How do we know what is extinct for sure?

So how do we know what's extinct and what's not? Well, even though we may not know a lot for sure, at least there aren't T-Rex's around! :)
