.and the first two of those five were invented by "men alone"...

How do you know that ? Maybe they were infallible ... after all are you infallible ?

and the first two of those five [i.e. sola Scriptura, sola fide] were invented by "men alone"...

[RnMomof7]
How do you know that?

By reading the writings of Luther and co., mostly.

Maybe they were infallible...

Where do you get that idea? And why would you even ask that, if you're doubting that the men involved invented the ideas? Either they invented those two false "solas", or they didn't; if they didn't, then there's not much point in asking about their alleged "infallibility".

after all are you infallible?

No. Why on earth would you ask such a thing?
