Answer 1

We can observe nature and we can make measurements of what we observe, then we can form hypothesis about why we observed what we did in a way that allows us to check the hypothesis against further observation, the result of that check then further informs our hypothesis and the cycle repeats. We can build deep and extremely accurate understandings of the natural world in this way and the most important part is that it is self correcting. The hypothesis are always advancing as each test is performed and the results examined, new questions asked and new observations made. In this way our understanding marches ever closer to the truth of nature.
