Agree with most of what you said except the "over 99% likely to be false".
Like you mentioned it's not possible to prove either way so it isn't meaningful to describe it as likely or unlikely. We have no way of knowing (at least currently) so the likelihood is simply undefined
Ah yes, the English language speaking race
Never heard that idiom before, (is it German?) Sentiment is clear though, I would probably just say "in its infancy" or something.
Also completely agree with your points. I'm a major supporter of FOSS but at the end of the day, I'm gonna use what actually works - the same as everyone else.
It sounds like you're referring specifically to Christian theology but the comment was just about whether a god or gods exist in general
