Questions about Origin and Evolution of Life

Why do you bother answering questions about Nibiru and other 2012 Doom's day stuff which anyone with basic education and common sense should discard as intrinsically irrational? Don’t you feel like if you’re wasting your time and people able to formulate such questions do not deserve any attention at all? Am I being so demanding with my expectations about people’s intellect?

(1) NASA predicts total blackout on 23-25 Dec 2012 during new alignment of Universe. AND (2) If Nibiru don't exist why are they spraying the sky with chemtrails to try cover it up? AND (3) The government and NASA could lie because you all know your safe you got your underground bunkers, but what about the rest of humanity? AND (4) I have read that the precession "ends" its cycle ever 26,000 years and that we enter a new equinox. AND (5) If NASA knew that something bad will occur, would it keep quiet so the population not to panic or would you tell the people?

Why did the government make an announcement not to worry about 2012? How come NASA nor the government spoke about 2000 or 2003 like this but seem dedicated to make sure we believe 2012 are a hoax. is this a conspiracy? AND If NASA is not worried about Dec 21, why did the head of NASA make a video warning NASA employees to prepare for disaster?

Is there any possibility of an existence of a planet in the same orbit of Earth, on the opposite side of the Sun and so we can never see it? If that was possible, how could we know about his existence?

I want to know how much truth is there in the myth of "the three days of darkness" that could fall on the earth. AND May I know if galactic alignment will occur this year? Some people say it will cause massive earthquake, tsunami, meteor impact. They say that this galactic alignment happens just once every 26,000 years.

How can so big satellite as moon can stand so close to earth and still act like satellite when our planet is too small to have that big satellite. I'm trying to think logically but here this matter then logic goes through window.

I am extremely worried about an asteroid or comet hitting Earth around 12/12/12 creating an ELE on or around 12/21/12 and I am also concerned that the Galactic Alignment that we are expecting on December 21, 2012, and the winter solstice eclipse at the same time as we are aligned with the super massive black hole at the center of the Milky Way Galaxy. I am worried that there are unknown events that NASA may not be able to catch ahead of time. Could you please answer my question and help to ease some of the tremendous anxiety and fear that is increasing daily.

I read that “December 21st the Earth will enter a ring called the photon belt. This will shut down completely our planet and we will have three days of darkness. NASA confirmed this yesterday, December 4th 2012. It is said that when darkness falls completely, it will feel cold and flashes of light will appear on the sky, and that this is a phenomenon that happens every 11 thousand years”. AND In all newspapers, internet news everywhere are some "new facts" about the end of world, government conspiracy to hide the truth, preparation of people in Russia and USA, buying shelters, food and water supply, it makes me sick even if i know that all it's stupid and irrational. I'm a mother of a 3 year old child and I'm 2 months pregnant as well. All this makes me very depressed, and I’m asking myself what should i do. My daughter is waiting for decoration of Christmas tree but I don't know will we need it at all. To be worse I have a young cousin who tried to commit suicide a week ago because she doesn't want to die suffering and facing the death of all people she loves. Please, sir I would like you just to help me explaining to her and myself as well that nothing out ordinary will happen, that we wont disappear in just one day.

If the northern permafrost begins to thaw faster than expected, will the release of the trapped CO2 accelerate the climate change scientists have been warning everyone about? AND Are the north and south polar caps growing or shrinking? I have heard both claims made. AND Can you explain why there's been a severe drought in the past few years in the US especially in certain areas and if our winters, particularly in the west, are milder?

While the U.S.governmemt has apparently been keeping the coming catstrophe secret, the governmemt of Russia has been telling people for weeks that the end of the world is happening this year. Do the Russians know something the rest of us are not being told about?
