Where do humans come from?
How did the universe begin?
If the Earth of really round, how come Chinese people don’t fall off, eh? Stomped now right?
When we don’t have a full explanation, when we don’t understand the detailed complex explanation given, or when we don’t even bother doing a basic research, the easiest thing to do is to point to magic.
Magic is a truly wonderful tool to explain complex concepts with no efforts. It doesn’t require previous knowledge or experimentation; you don’t even have to open a single book! It is easier to invoke magic than to listen to arguments, understand the underlying principles or look at the evidence. You can also substitute the word “magic” for “God” if you are evangelical.
