My guess is that his "knowing" is emotion-based and at best his results are inconclusive.
The alternative would be that he has clear evidence supporting such visitation, and I find it difficult to believe that such a thing could be kept under wraps.
Personally, I don't care if Robert Bigelow believes in the Loch Ness Monster as long as his company can produce viable habitats for orbit and beyond.
"The FAA confirmed to us that for years, it referred reports of UFOs and other unexplained phenomena to a company Bigelow owns. He told us he's had his own close encounters, but declined to go into detail."
