The Hiligaynon people, like many cultures, don't have a scientific explanation for why the sky is "high." Instead, their understanding is often rooted in mythology and folklore.

Here are some possible explanations based on Hiligaynon beliefs:

* The Sky as a Dome: The Hiligaynon might see the sky as a giant dome that covers the earth. This belief is common in many cultures and can be traced back to early observations of the celestial bodies.

* The Sky as the Abode of the Gods: Hiligaynon mythology often depicts the sky as the dwelling place of deities. This idea connects the sky with the supernatural realm, making it a place of power and awe.

* The Sky as a Symbol of Immensity: The vastness of the sky can be seen as a symbol of the unknown and the boundless. This sense of wonder and mystery may lead to a perception of the sky as being "high" and unreachable.

It's important to note that there is no single, definitive Hiligaynon explanation for why the sky is "high." Their understanding is likely a combination of these beliefs and personal interpretations.

It's also worth considering that the term "high" in this context might not be literal. It could be a figurative way to express the sky's vastness and its perceived distance from the earth.
