@TheEnlightenedOne,
That word "existence" is always the issue which is avoided in the countless questions of the form "Does X exist ?".
Choose one or more of the following concepts of "existence", or add your own to the list.
(1) X exists because it has
materiality
(2) X exists because it is a
useful concept.
(3) X exists because it is in
relationship to Y.
(4) X exists because it was
created by Y
(5) X exists only experientially in the minds of
sentient beings.
(6) X exists because
we can talk about it.
