I am not really too worried about being "logically coherent" with this question. I am sure if you just used your imagination a little you can grasp the concept of a created existence.
No, I really can't. I think "created existence" is as logically contradictory as a square circle or pacifist war. Creation implies a creator, which implies the existence of a creator... but if the creator exists, then "existence" can't be created, since it existed already.
And it's not like existence is a "thing" that can be created anyhow.
Billions of other humans do it, I am sure you can as well. Perhaps you are being to encompassing with the term "existence". Could you imagine something not of existence creating existence?
No I can't, because this statement implies that this "something" exists. When you describe it as "something not of existence", you don't resolve the problem; you set up a logical contradiction.
It does not exactly have to be a well developed notion to address the question.
Well-developed, no. Not inherently contradictory, yes.
The question is meant to be aimed at what humans knows, it is a question about human knowledge. Do humans possess knowledge of what created existence? If it is that existence is not created then clearly we do not possess that knowledge.
But we also do not lack the knowledge, since there would be no knowledge to be had. If existence is not created, then your statements in the OP effectively turn into the logical equivalents of "divide-by-zeros" - their truth value is undefined.
And they're
especially undefined as long as they contain logically incoherent terms.
"'I don't know'"
Which would mean you have an absence of knowledge.
An absence of knowledge about
the question itself, not necessarily an absence of knowledge about the subject of the question. The question needs to be defined better before that can be determined.
It's as if someone asked you "do you know (incomprehensible foreign statement)?" Your answer to this question has to wait until the incomprehensible part has been properly defined for you. You can't give a knee-jerk response of "no", because if the question turns out to be something like "do you know your own name?" then the correct answer was actually "yes" all along.
