Evidence sir.
“Extraordinary claims require extraordinary evidence.” -Carl Sagan
I have been crunching radio telescope data for many years now looking for that evidence in the most logical way possible we can think of right now....

That answer may never come, we could be utterly alone, or seperated by vast distance or time for that matter.
But your wont find evidence in books people write or TV shows or converting people on forums into “believers”.
When the facts change, I change my views, what do you do?
That's making the stupid presumption that you're informed of the facts and are in possession of the physical evidence. Carl Sagan is right, but forgets to mention that extraordinary claims and evidence will certainly inspire extraordinary opposition. I have no doubt, nor did Gordon Cooper, for example, that the government has taken such extraordinary measures. For good or bad (I tend to think for good), but extraordinary is as extraordinary does. Sagan's quote is moot.
You ask what I do. I base my conclusions on independent thought and trust my common sense, imagination, and instincts even when they are inconvenient and unpopular. I've done well by myself in trusting my ability to be an original thinker. I figure I'm in good company. Much of the best science in the world has been inspired by imagination and instinct. If I remember correctly, Einstein said as much many times.
I'm impressed that you crunch radio telescope data, but not impressed that you think that covers everything, including the human element. I repeat that Scott Peterson's lawyer would have liked to have had you on the jury.
