We can recognize moving things with our hands while also imagining our non-existent telekinetic powers. I don't see why the same could not be true for good and evil.
Because good and evil are not things; they are qualities that we assign to things. If you never had an example of the contrast between good and evil, you would never understand that these qualities could apply to things. Just as if nothing was ever unjust, we would never have developed the concept of justice.
The difference would be doing what you are not currently doing. Am I currently not going on a raid of a local town, raping and pillaging the town folk? Nope. So good would be not doing that, which is what I am doing now, and evil would be participating in a raid.
If there was no concept of good or evil though, participating in a raid would be just as "good" (and just as "evil") as not participating.
Yes. It's not that hard to build a model of small particles bouncing off of an object. We also measure and model light that we can't see, such as x-rays, infrared, and radiowaves. The entire enterprise of science often can describe things that we can't see.
It's not about "not seeing" light; I said if light did not exist. Why would anyone think that there was such a thing if it did not exist, and why would anyone think that it could arbitrarily be modeled as small particles (or even waves) bouncing off of an object? You're only able to say that NOW, because you already have a pre-existing knowledge of light. If you had lived your whole life without it, and without a sensory apparatus to detect it if you ever did encounter it, you wouldn't have a clue what the word symbolized.
So there will be evil in heaven?
There will be the concept of it, thanks to our experiences on Earth that will allow us to appreciate the complete absence of evil in the presence of God.
