Expressing skepticism and questioning your fantastical claims of the existence of space ships is not creating a positive claim. It is questioning your positive claim. It is the party bringing those things as evidence to the discussion who must meet all challenges.
If NASA claimed to have landed on the moon and had provided no evidence to that effect. Then yes, I would agree, the burden of proof would be on them. But once they provide large quantities of evidence and you claim that evidence to all be fake, then the burden of proving the fraud is on you.
You nailed the problem on the head - no evidence is valid unless it supports FET. Decades of peer-reviewed science isn't proof of a round Earth, but some random video on youtube confirms, without a doubt, FET. Convincing people like Tom is out of the question. You could put him on the ISS and he would still find a way to claim the Earth was flat.
Actually, that is incorrect, what NASA does is not "peer reviewed". That is one of the many criticisms against them. There is also much criticism of the evidence on the internet elsewhere.
The sticking point for me is that the legislators who created NASA were also caught conducting a secret war. Those same legislators also put Nazi war criminals in the NASA administration. Why should we trust a word from them?
And, yet, here you are you are telling me that I need to prove that those seditious politicians and Nazi monsters are dishonest... Very funny.
nasa has and does publish things in peer reviewed journals. who made your microwave? is that technology still a nasa secret, or has it made it out to the general public?
