It is puzzling how some people have such a hard time with the fact that results are entirely independent from explanation. A small child flips a switch, and the light comes on. That child has no understanding of how light bulbs or electricity work, yet the light comes on every time (unless someone forgot to pay the bill 😉).
Scientists conduct experiments, and observe the results. They then seek to understand and explain those results. The results are the same, before and after the explanation. The results don't wait until there is an explanation to manifest.
