Cosmology, like many sciences, is about learning the scientific truth through the remnants left behind. Just like we can see an early earth by digging, we can see an early universe by zooming.
A well reasoned theory in any science should include and test for implications in the past and present. We can't just ignore time if we want a proper understanding of the universe.
