Update / More interesting, voting over there, betting over here. Although we believe in something, we know nothing at all. Here’s a cold sci-fi joke that reminds me of 'Dune'. On the desert planet, besides the desert, there are sandworms. And rain is the substance beyond that planet's cognition. There’s a part of the story: the desert heroine Chani asks Paul a question, 'On your planet, does water really fall from the sky?'

Paul is a master of charming women, with a melancholic temperament and poetic flair. He tells the heroine, 'Of course. On our planet, water falls from the sky, it’s called rain.' The male lead says it can sometimes rain for several weeks without stopping. Our castle is built on high cliffs by the sea; if you jump in, you cannot reach the bottom of the sea. This is called swimming.

'You can think of the sand in front of you as water.'

The beautiful heroine says, 'I don’t believe your words.'

For things beyond our understanding, no matter how others describe them, they sound like lies. The way Paul speaks is like the elders and shamans gathering around the fire in ancient tribal times.

Some things have happened in the past, with historical playback seeking the truth. Some things will happen in the future, with technology hinting at trends. Today we observe some things, and even with excellent tools, it often requires a change of perspective to see them.

In short, what I want to say is that someone must have known long ago.
