No it isn't, because your example assumes Australia is so intangible that it is
outside conventional reach. I can fly to Australia; I can live stream with a friend of mine who can traverse Australia for me, even.
The moon is a particularly difficult place to reach without clearance, and an incredible means of travel is needed that is not available to the general public. Therefore, it is a matter of faith to trust the words of those
very few persons who have seen the Earth from beyond low orbit, or have been to the moon.
If I told you:
I have been to the Pleiades, and it shaped like a dodecahedral with spokes on every odd face. My proof of this is a picture I took using my low-orbit antigravity machine to reach the planet, and an enhanced lens camera to take the pictures. But, before I took give the pictures to you, you should know I edited a few things using photoshop.
Now, believe me...
your difference in incredulity is that you trust the NASA name, not me - which is perfectly fine. But, that is an exercise in
faith, not necessarily truth. For me, I would need an untouched, raw photo, and then eventually to see it for myself.
And even the, I believe none of what I hear, and half of what I see - especially from humans.
