What's the alternative? You mentioned three things and them refer to them as "it" in the singular. Reasoning is one thing. It uses empirical objective evidence and logic to reach conclusions. The beauty of logic is that given true premises and a valid argument, the conclusion is deterministically true.
We don't always get evidence that lends itself to deductive logic, in which case we resort to inductive logic. We use induction a lot more than deduction. In induction we look at a set of data and impose an explanation that makes sense of it.
The short answer to your question should be obvious: it works.
