i see your point
but
when i wrote “i am a liar”
i meant it in the sense of a liar who lives in Riddle World
as you know from other riddles here, those type of liars always lie and cannot tell the truth
therefore if his statement is true, then he is a liar and his statement is false
if his statement is false, then he is not a liar and his statement is true
a paradox whereby the truth of his statement is immpossible to be determined.
this is not the case with “my father is daniel” where it is possible to determine its truth value
a better way of making such a statement, where we dont have to follow riddle world rules would be “the statement that i am currently making is a lie”
do you understand why that statement cannot possibly determined to be either a truth or a falsehood, why it must be neither?
