Actually most people dont know that "its" is a word.
And no offense but since your general level of literacy is so so in English, Im sure and hope you have a native language, its highly unlikely that youll know this small fact and the various distinctions between Its or It's, your or you're (or yore).
Kind of telling us a lot about yourself by pretending to know this fact. Its not even a big deal to not know this, but to pretend not to know it is undesirable.
