So, we know of animals that have much longer life spans than humans do. But how do we know that certain species live to be an average of something like 175 years old if nobody is alive long enough to observe it that long?

The same way rocks are dated.

They can tell by the fossils, and they can tell how old the fossils are by the rock surrounding them.

So they can tell how old animals are by comparing them to other animals age around them. Then they determine the age of those animals by comparing them to the old ones.

OP didn't mean geological age/time period.
OP meant life span of a single organism.
