Think about the beautiful skies, any, morning, evening, red, blue,
filled with fluffy white clouds, or menacing dark ones,
dancing with shimmering lights as auroras. No one will ever touch them
and the closer you get to them, their shape will ever change and
never look the same as from the ground. So even if they are real
as seen from ground level, they are and ever be intangible to us.
They will only be an image in our minds. Only we humans are capable
of looking up and understand this, that each scene will always
be just unique projections in our minds, never the same,
intangible, every time, now, then, and in the future.
