How does google read text?

Ok so how does google actually process text

"The man at the end of the street."

"The man in the end of the street."

So google looks at this and can auto figure out that the second one is wrong and a man can't be in a street?

does google realy know every sentence in the world even ones that do not exist?

How does google realy see articles?

I've always wondered the same thing. I was once told that Google doesn't really read the text, they determine if the content is up-to par based on if the user returns to Google to continue searching on the specific topic. I would like to see what people have to say about this too.

They then check for spelling errors and such and then write a report to mr google. He then gives your website marks out of ten.
