How do I respond to someone who thinks that anyone who believes opposite what you believe is lying, drunk, or on drugs? I guess these guys were lying as well: http://www.youtube.com/watch?v=clSciMFcmko
Also do some research and learn how the and why the National security council was created- it was primarily the result of Roswell. Also, you have already admitted that there are numerous stars/ galaxies, etc- so in your mind even though there are billions of stars- many other galaxies with planets- yet only little ole earth has intelligent life? LMFAO- even the most skeptical scientist would believe that chances are we are certainly not alone. Learn how to debate instead- of he's lying- they l drunk- how come I never seen one- etc

I said there have been NO alien visits to earth - or at least no proof of it. And the reason for that is that the "witnesses" are either liars, druggies or - occasionally - normal people who simply misperceived something.
I'm not going to watch that whole 15 minute video link, but from the parts I skimmed, it sounded like the officers were reporting what someone ELSE saw. One officer said that 3 airmen reporting seeing lights in the woods and saw a triangular craft that was 3 meters on a side. That is barely 10 feet. How could something that small be an interstellar space ship? How about a drone (man-made)?
And Joe Bloe got to the truth of it. Even traveling at the speed of light, it would take you 4.2 YEARS to get to the nearest star (Proxima Centauri) - a distance of 4.2 light years..
But that doesn't even account for how long it would take to accelerate to the speed of light. If you accelerated at one g-force constantly (i.e., the force of gravity) it would take you 354 DAYS to accelerate to the speed of light. That is almost a year just to reach the speed of light. And in that time period, you will only cover one-half of a light year. Then, at the opposite end, you have to reverse the process. It will take you another 354 days of decelerating, during which time you will cover 1/2 light years.
So, to get to the NEAREST star, it will take you 5.2 years, not 4.2 years, due to the accelerating and decelerating. Even if you accelerated and decelerated at twice the force of gravity (which would make you nauseous), you would still spend 4.7 years traveling.
None of this accounts for the phenomenal amount of fuel required to accelerate and then decelerate constantly for a year just to get there. And, of course, they would need the same amount of fuel to get home. So the engines would have to be massive just to accelerate that much fuel mass at the 9.8 meters/second rate of gravity. So the spacecraft would have to be immense just to deliver a tiny payload.
But, in reality, you cannot get to the speed of light because as an object gets closer to the speed of light, its mass increases. As it gets infinitesimally closer to the speed of light (99.999%), the mass increases towards infinity. That means it gets harder and harder to accelerate the object (i.e., its heavier). That is why you cannot ever get to the speed of light. So, MAYBE, you can accelerate to and decelerate from one-half of the speed of light. But now your 5.2 year journey to the nearest star is well over 10 years and that is in just ONE direction. The return trip is another 10+ years.
This doesn't even address the problem of how an alien race would know we were here in the first place. They would have to detect our radio waves, which we have only be transmitting for about a century. So the only aliens that could detect us would have to live within 100 light years of us.
But if they were so advanced that they could build a spaceship that could get here, they also would have been transmitting radio waves even longer than us - more than a century ago. So, we would have detected their radio waves by now and WE WOULD KNOW THEY EXIST ALREADY. But we haven't detected any such radio waves, so that means there aren't any advanced civilizations within 100 light years of us. But that probably rules out only a few dozen stars.
However, since our radio waves have only traveled about 100 light years, that means our radio waves have NOT yet reached any advanced civilizations that are more than 100 light years away.
So, if an alien spaceship actually DID reach earth, then it found us strictly by blind luck. There might be intelligent life located near one out of every 100,000 stars. What are the odds they hit us by blind luck?
And why would an alien civilization ever incur the phenomenal costs of building such a massive space ship, just to send it out into space at random and HOPE it finds something. It would take any such alien space ship over a century to get here and therefore take over a century to get home. So the trip is a one way trip for the aliens on board.
If it were humans, they would have to spend a couple of centuries away from earth - assuming they could get anywhere near the speed of light, which they cannot. So, it would be more like 4 or 5 centuries away from earth. Although time would slow down for them at say, one half the speed of light, they would still experience a couple of generations - maybe a century - on board the ship. So the humans on board would have to breed another generation on board, raise them inside a ship, and train them to be astronauts.
Who knows? Maybe they could deep freeze the humans on board and wake them up 2 or 3 centuries later when they get near an interesting star where there may be some life. But you still have to build a space ship and freezer units and all of the other equipment that will last for 500 years without breaking down. Or carry spares for everything - which make the space ship REALLY big and heavy. A lot bigger than 3 meters on a side.
You will spend your entire life cooped up in a ship with a high likelihood of dying without ever returning to earth. If you DID somehow get back, everyone you know will have been dead for centuries.
The point is, this is an impossible undertaking, so no one would do it. Not even the aliens. It is a huge cost for an almost non-existent reward. What nation or group of nations is going to spend 10 of trillions of dollars to build an enormous space ship that will disappear for 500 years or more and MAYBE come back and announce they found something like moss on a remote planet?
We are marooned here forever. And the aliens are marooned on their planets.
And those are my science-based reasons for saying there have NEVER been alien visits to earth and probably never will be.
What do you have? Unexplained "paranormal" events and ghost sightings? From celebrities who have no reason to lie? Do you really think you are involved in a debate?
