No, they don't hold up for anyone using science as a tool. Umm yes, maybe they move to fast to be seen. Maybe they don't exist
You are using science as a tool yourself? Exactly what evidence are you considering? none. You sit at home, do zero research and presume that all you know is all that can be and prounounce you've used "science".
That's not science. That's swallowing what you've been fed by the most easy means.
Government has had very little success for hiding secrets for a long period of time? Take a look right under your nose! Last February Clinton issued an Executive Order that was removed all Civil Liberties in the event of a "National Security Crisis" and removed the previous state of Martial Law with its military tribunal (trial) and allowed any and all citizens to be imprisoned without any reason nor explanation. .. and it slipped right past you!
WHY would a President who had just been impeached, and was a lame duck president and SHOULD have been worrying about his legacy go to such an extreme to issue such an executive order ---- unless he felt a particular *singular event* loomed on the horizon?
Perhaps you have not seen the evidence from the Roswell crash .. yet it exists.
What is it you DO know?
Man has landed on the moon -- and as yet has not had any fact-to-face conacts with these "aliens". Are you so sure? What did happen with the moon?
HOw about considering THIS image from a NASA web site?
This image is a Moon walk of Apollo 12, the second moon landing obtained from an official NASA site. See anything extraordinary in this image? Look for yourself before going on.
[ANSWER - There are t h r e e astronauts on the moon surface! There should only ever have been TWO on the moon surface as the LM could only hold two, the third always aboard the Command Module circling the moon and having to operate the manual docking doors.] What's extraordinary about this? Give it some time and perhaps it will come to you.
There is tons of *HARD* info out there about what has been going on and continues to go on. Go as far back to the biblical story of "Sodom & Gomorah" and you can read an accurate description of a nuclear mushroom cloud..and hear how the earth is to be "salted" for generation after generation and nothing will grow (irradiated soils) and hear how Ruth is warned if she turns back she will be turned to a pillar of "salt". Curiously, in ancient Aramaic the world "salt" and "ash" are exactly the same.
Were you paying attention you'd know that in the last 15 months the NSA (National Security Administration) has had to black out images from NASA's own SOHO satellite which images our Sun. What could be of national security interest on the proximity of our Sun? You should see the unedited imagery -- it is nothing less than mind boggling.
Where's your science? It is only a convenient word to cover your failure to get off your arse.
The *TRUTH* of what is on Mars is on Mars UnEarthed
..and it shows current, imediate activity and undeniable artificial constructs.
