Do you believe; and why?

Heuristically speaking. That all is severely more complicated than that and this is the point where I should stop being educative about things I know very little about myself :)

...but it isn't quite like evaporating water. Evaporated/gassy H2O still is H2O and still has the same mass. With nuclear fusion, that's not the case.

LOL that energy "raining" down from the sun though, some of it is reconstituted as mass, right? 

Actually, I think that when we are talking about individual subatomic particles, there is no loss or gain of mass in this transfer, even when fusion occurs. I think.
