Is Every Website Potentially "Hackable"?

[St4nley]

This question has been on my mind for years now, every since i knew little of computers but i knew what hacking was this thought always came to mind.
My idea of hacking is no, not a DDoS attack, but some sort of manipulation where the "hacker" can edit, or enter some sort of context. My general question is towards more advanced websites, which i mean arent just written HTML, where the output is the given text.

So what do you think? Do you believe every website is hackable whether it be Sql Injection, URL Redirect, Cross Site Scripting or any other of the hundreds of hacking options.

I believe there is a way to hack the majority of sites, some are just harder to do than others. It comes to the knowledge of the hacker and the website administrator - I know very little about hacking, so it's just my theory.

Google is un-hackable, big websites like facebook have been hacked before, but the hackers couldn't do that much damage and facebook came down fast and hard on the hackers

No, every website is not hackable, what a silly theory. From time to time a website(s) may have a vulnerability, but that's by no means the norm.
