Here I found an answer two months ago, which I forgot to forward it to you :)

I beg to differ. A cathedral is a cathedral. A painting a painting and a photograph is a photograph. I can't experience any of it in the inside, if I haven't experienced it already in real life.
I can only make comparisons if I have two things to compare to one another. One real, one virtual.

A man, who grew up in the jungle and never in his life has seen a ship won't know it's a ship. He could not make any virtual connection to its purpose, function and parts.

The real thing is not in any way similar to the virtual. If you think about it in depth, there is no such thing as similarity.
