There are more galaxies in the known universe than all the grains of sand on earth. Each one containing billions of stars, most of which have planetary systems. The numbers involved are literally unfathomable.
The sheer numerical odds overwhelmingly favor life elsewhere in the universe.
I'm reminded of the book, "Rare Earth", which argues that simple unicellular life is very likely quite common throughout the universe, but complex life...not so much.
I suppose if you believe the universe was created in a random manner.
Knowing how crap works in Washington this is being done to “soften us” tot he idea that aliens exist because our government made contact in the early 50’s, probably made contact with multiple space faring species and then formed a pact with the one that probably promised the sick bastards in washing to most amount of goodies instead of the ones that said “we can help you but you gotta be responsible and work hard etc...” we probably got betrayed in the 60’s when the aliens didn’t deliver fully and overstepped their bounds on the “treaty” that was made with them by abducting more than they were supposed to do or something like that.... Which all led to the government really clamping down on any alien existence information...
Why...
Well because then the politicians in Washington would have to admit to betraying us...
Why...
Because all the FDR socialist politicians were chumps who didn’t realize they were going to be screwed by ETs.
Why now...
Because most of the Politicians then are almost all died off and they current corrupt bastards think they can sew unrest by eventually exposing the existence of aliens to the nation....
Oh don’t worry, they will still fight like hell to prevent us from knowing how badly we were initially screwed over by them....
I think you're right. Modern science is daily providing informtional facts indicating the truth of Darwin's evolution theory.
Recommended reading: "Darwin's Ghost" by Steve Jones. It's a modern update (377 pages) of Darwin's work that's loaded with newly discovered facts supporting Darwin's theory.
