If you weren't the grammar teacher's pet

If he was sober and impartial he might tell you  there is no such word  , therefore you are  
"the one"  lacking  existence .  

Why do senile  teachers favor the student who agrees with him ?  

   Because the demented  swallow agreement with their flock , like a drunk with wine .

 Why did the scientist become fat and fall down ?  
   
  Because he confused milligrams with  kilograms in his new and improved diet .  

 Why do millions die from legal  prescription  drugs ?  
  It's not a joke  

  Oops my bad , after more research  I found existance in the dictionary .  
" existance "
This is the wrong way to spell "existence". There is no "a" in existence -- or in definitely, for that matter.
Maybe if you weren't functionally illiterate, you'd have a more "excellant" job. "

I suggest you come to terms with your lack of understanding before continuing your palaver
