Just read a comic,

"現實"的理論, 無法解釋"非現實"的事物

I remember when I watched Star Trek, someone was trying to explain what is happiness to an Android without using "emotion" wording.  Conclusion: he can't.

Just like non Christian common phaeses: "I can't believe until I see or understand"

How do you see God who is not an object limited to a 3 dimensional space like us?
How do you understand something that is outside  human limits?
