Roswell

Sixty-six years ago this month, according to some, an alien spacecraft-- or two-- crashed in the desert outside Roswell, New Mexico.  Put another way, we are now roughly the same time period removed from that alleged crash as Apollo 11 was from the first heavier-than-air flight at Kitty Hawk.  An awful lot can happen in 66 years.

We know vastly more about space travel, the universe, and the odds of other intelligent life in the universe now than we did in 1947.  Space travel is now a fact, and interstellar travel is almost certainly possible.  The universe could well be teeming with life.  That may or may not increase the odds for technology-producing intelligence, but the universe produced one such species-- us-- so others are perfectly possible.

Do the advances made over the past six decades make the Roswell story more plausible?  Broadly, yes.  However, to prove a specific event actually happened requires specific evidence.
