Certainty and uncertainty

There is no "proof" or "disproof" of anything.  There are only opinions with varying levels of confidence.  "Faith" and "belief" are for those who want to have certainty but they are denied it in spite of their self-congratulatory self-deception.

I tend with a few exceptions to follow the views of the experts -- those who have spent their lives studying the subject -- more on the hard sciences (physics, etc.), less things like biology and almost not at all with religious and paranormal and political and historical "experts" who have an agenda.
