Actually not even the brightest geek or nerd could explain why the Internet is not real, still, I'd like to see you give it a serious go.
I believe you would have to start by defining your interpretation of "real" and "not real" how you differentiate between the two and what criteria must be met for something to fall clearly into one category or the other. Of course you won't do that, because your belief is based on vapour, but if you could I might be tempted to take your argument that the Internet is nor real more seriously, since you would have had to establish justification for the statement and explain the implications should that statement be upheld as true.
