An old coworker of mine tried to convince me that he was capable of running what math'd out to be a 3:45 mile. (the original claim was that he ran x amount of miles in y minutes). That would be an impressive boast under any circumstances, but he also weighed around 300 pounds. His brother, who was also present, got extremely upset when I scoffed at this claim. He said "You weren't there, so you can't say whether or not it happened," a pretty direct parallel to your quote here. Additionally, he stated that it was infuriating when people who didn't experience thing questioned someone else's experience of thing. This also seems to be a narrative in your posts here.
Regardless, his obese brother could not, and therefore did not, run a sub-4-minute-mile. We don't need to be present at this race to conclude such. We have ample evidence of the physicality required to accomplish this feat. The same holds true for supernatural claims.
