Maybe `The Great Filter`` is there because being the way we are here on earth they don`t want to be found.

Hanson of George Mason University posits a "Great Filter" that prevents the rise of intelligent,
self-aware, technologically advanced, space-colonizing civilizations.
The "filter" would be one or more improbable steps along the path that
starts with the creation of a planet and ends with a race capable of
colonizing the galaxy.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2009/02/does-a-great-fi.html">Somewhere between those two points,
philosopher Nick Bostrom points out, "the Great Filter operates, and it
must be powerful enough that even with all the billions of possible
starting worlds on which life might evolve - all those rolls of the
cosmic dice - one ends up with nothing: no aliens, no spacecraft, no
signals,</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/F7271C5D-50EF-4F0F-BD1F-01DE90F6E83F/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
