I'm writing an essay regarding the concept of Carpe Diem and I'd like to start my introduction with the following sentence:
"In the span of the universe, a human life is an incredibly short period of time."
I feel like I'm using "in the span of" wrong. What I'm trying to get at is that the length of a human life is a very short amount of time when compared to the lifespan of the universe.
Any help regarding the matter would be greatly appreciated.
