If you want to pursue knowledge there are some risks and investments needed in this matrix-system.
Maybe you prefer the statement 'ignorance is bliss'?
Sure, but given that the knowledge you're offering isn't anything particularly useful...
After all, even if there is a place that fills in for Australia, that just means the Mojave Desert exists, rather than Australia.
You are not prepared to put in the efforts, investments and risks to figure out if Australia exists and where it is located on the planet.
If you did you don't get the guarantee that you will find the answer. You are not willing to do anything.
That's fine, nothing wrong with it, but your statement 'Australia does not exist' is nonsense.
If it does not exist the statement has no meaning.
If it does exist, it is not true.
So, why not say 'I don't know if Australia exist'?
Or better, not to say anything (and not ask the question).
