evidence and proof

if there is no proof to its existence, no scientific notion just simply a hint or impression by those that

want to think it true then does that mean it doesn't? If you think it so then is it? if you think it not so

then is it not? If all your thinking has no proof then do you? If you give something a name yet there is
no proof that the name given to it is what its name is then is that its name?

Is lack of a name and 

evidence of such name proof of non-existence.Is no proof of existence proof of non-existence. If I

have never known you, heard of you, spoken to you, then does that mean you don't exist?

if you said to me one day

"Hi my name is (?)", would it then be acceptable for me to say prove it?

what will you say then "i am me because that's what I call myself and everyone who knows me calls me this and this is me standing in front of you".

Could I then say I see nothing hear nothing and am simply reading words that someone wrote for you
with your dictation and influence, but you do not exist?

Could I also say then that because you live on the other side of the world and I have only heard of

you through stories, then could I say that you do not exist.

 Now if it is permissible to decide that you do not exist, based on evidential truths would it then be

true, with truth being self evident and you being without evidence of you, only existing through

others writings, would you then be truthfully non existant? just wondering.
