Absolutely not true.
I really, really wish I was being paid, but I'm not. I'm sorry.
Plenty of FEers insist REers here are being paid. Would our word convince you? That's exactly what a shill would say...
1. You can go to Australia tomorrow. You can't go to space tomorrow.
Go ahead then. Just because you're told something's possible does not mean it is.
2. There is no incentive to maintain an Australia conspiracy. Space travel, when the Earth is flat, yields people billions of dollars.
You have heard of the tourism industry, correct? Space travel nets far less than that, especially once the cost of actually building huge rockets and paying off sources is taken into account.
3. It would be too large. I can go on the internet and find people on Facebook who say they're from Australia.
It's on the internet, so it must be true.
5. There are just too many people in contact, or who claim to be in contact, with Australia.
How many is 'too many'? How many have personal experience, that you know personally?
6. Plain observation can confirm that Australia exists, as well as the Earth being flat.
Given that photos may be manipulated, and that you have never personally seen Australia, give one example of how plain observation can be used.
7. Australia is part, and a contributor, to the UN.
8. Most developed countries have some diplomatic relations with Australia.
Perfect way to get money then. An ambassador shows up, wow: doesn't mean they have to be from Australia. The current PM of Australia was actually born in London. Coincidence?
It is absolutely not a parallel.
It is a false equivalency.
It is a parallel to many FEer points. The focus on personal experience to the exclusion of trusted sources, for example. It goes further, yes, but the same logic is applied.
