There are all kinds of puns that could be made of either political party, but I resist.
Perhaps you didn't know it, but the White House website permits individuals to submit a petition. A petition consists of a maximum of 800 characters as described in the step by step guide. If a petition receives 25,000 signatures in a 30 day period, the White House will research the issue and provide an official response.
You can search the open petitions and determine if it is something you would be willing to sign. For example, one of the 120 open petitions is - Require all Genetically Modified Foods to be labeled as such. Today it has 9,658 signatures.
But I digress. Searching for ET, But No Evidence Yet is a formal White House response to the petition, "formally acknowledge an extraterrestrial presence engaging the human race". The response explains there is no coverup - there just isn't any evidence of life outside planet Earth. The report tells that NASA originally participated in SETI (Search for Extra Terrestrial Intelligence), although it is now privately funded. NASA has launched the Kepler spacecraft to search for planets that could support life and the Mars Science Laboratory will be launched to investigate possible precursors or history of life on the red planet.
The White House response concludes noting that many scientists consider the trillions and trillions of stars as evidence there must be life outside of Earth. But many of these same scientists caution the probability of bumping into extraterrestrial life as remote. The response is signed by Phil Larson, who works on space policy and communications at the White House.
