Using the principle of Uniformitarianism, which makes the most sense?
A) A crater from 4 million years ago is similar to one from an impact last year; the ancient crater probably wasn't caused by an impact however.
B) A crater from 4 million years ago is similar to one from an impact last year; the ancient crater was probably also caused by an impact.
C) A crater from 4 million years ago is similar to one from an impact last year; the ancient crater must not be as ancient as scientists thought.
D) A crater from 4 million years ago is similar to one from an impact last year; the new crater must be a lot older than scientists thought.
