The possibility of error does not necessitate the existence of error. "100% proven facts" are few and far between. The idea is to simply lower the room for error as much as possible.

In this case, there is not much room for error. I don't have SE's server client in front of me, but I also don't need it in front of me. You talk about "research" and "valid arguments", but you make it abundantly clear that you have no idea what you're talking about. That's cool I guess. A valid argument is just an argument that can potentially be true in some possible universe. So I guess you have that half down at least.

It's just not true in this universe.
