So according to you, as long as a group of you all agree on something,  using your 5 senses, then that makes it a fact?  No, it makes it an opinion (group opinion) that may or may not be a fact.  Data can be unreliable as it can be affected and changed by external forces. Reality to one's self does not make it fact. I guess we may have to disagree on this one.  What else is new though ;-)
