If you're actually interested in this topic, you should read "What is this thing called science?" by Alan Chalmers. One big take away from the book is that there are many things that are "factual" and "scientific" but are not "falsifiable". It's been an important part of modern scientific advancement that falsification is a good, but not perfect way of learning about how the universe works. For example, macro-evolution is basically unfalsifiable, and yet it is generally regarded as good science.
