From the Ted Talk by David Deutsch: A new way to explain explanation
Unscramble the Blue Letters
If the ancient Greeks had found out about seasons in Australia, they could have easily varied their myth to predict that. For instance, when Demeter's upset, she bnhasies heat from her vicinity into the other hemisphere, where it makes summer. So, being proved wrong by observation and caighnng their torehy accordingly still wouldn't have got the ancient Greeks one jot cloesr to understanding seasons, because their explanation was bad — easy to vary. And it's only when an explanation is good that it even matters whether it's testable. If the axis-tilt theory had been reeftud, its defenders would have had nowhere to go. No easily implemented change could make that tilt cause the same sesanos in both hemispheres.

Original Text
If the ancient Greeks had found out about seasons in Australia, they could have easily varied their myth to predict that. For instance, when Demeter's upset, she banishes heat from her vicinity into the other hemisphere, where it makes summer. So, being proved wrong by observation and changing their theory accordingly still wouldn't have got the ancient Greeks one jot closer to understanding seasons, because their explanation was bad — easy to vary. And it's only when an explanation is good that it even matters whether it's testable. If the axis-tilt theory had been refuted, its defenders would have had nowhere to go. No easily implemented change could make that tilt cause the same seasons in both hemispheres.
