scientific Fact IS educated assumption. "Proven" in the sense you are suggesting does not exist. What you are argueing is moot, because taken to it's fullest reason it negates the validity of existence. Anything that makes the quest for knowledge futile isn't worth exploration. That is why what you are saying is bullshit.
Prove what my astronaut friend saw wasn't reality. Prove that he can see. Prove that he is alive. Prove that he even exists. Prove that you exist.
The evidence suggests all these things are true. Only you suggest otherwise, because they cannot be proven to be true.
Using your definition of proven, of course. The actual definition is quite different.

the first definition is "to establish the truth or genuineness of, as by evidence or argument: to prove one's claim." and the others are much like it.
Proof has built into it's definition evidence. The Evidence points to a round earth.
My astronaut friend sees is as such. I can fly/sail around it. Satellites orbit it. The other planets would appear to be them, as do all planet and greater size cellestial bodies. (Other then nebula, which you are free to argue the earth is if you wish)
If the earth were flat, you would have to explain what makes it appear as a sphere to all instruments and observations. You would have to define some mechanism as to what bends light relative to where a person is standing specificly to them, while also bending it to someone a thousand miles away, is such a way that it matches up perfectly with a sphereical earth. Which is how GPS works.
A plane of GPS satellites could be tricked, What makes them link up around the edges seamlessly. Are there indeed edges?
Explain it. If your devil's advocate theory holds rational and mathematical creedance, you should be able to prove it. In the scientific sense. In the defined sense.
