The Ilocano language, like many others, does not have a specific proverb or saying that tackles this literal concept. It's a question that falls more into the realm of scientific explanation rather than cultural folklore.
If you're looking for an Ilocano expression that might be related, you could consider:
* "Naimbag ti langit" (The sky is good) - This expression is used to describe a beautiful, clear sky. It doesn't directly answer your question, but it highlights the appreciation for the sky's appearance in Ilocano culture.
* "Nadakkel ti langit" (The sky is big) - This phrase simply describes the vastness of the sky, but it doesn't explain why it's high.
It's important to note that Ilocano culture, like many others, has rich oral traditions and folklore. If you're seeking a unique Ilocano perspective on the sky's height, it's worth exploring stories and myths passed down through generations.
