Question

What evidence do you have that proves "grey" aliens DON'T exist?

Answer 1

I thought for a moment that I had gone into the Religion category. Science does not try to disprove the existence of anything. It is up to the believers to prove something exists. The ball is back in your court. what proof do you have that such stuff exists? I see that astronomy and the theory of relativity show that ET aliens cannot visit us. Study these subjects well, and you will learn why. You will see the evidence fot yourself if you study hard.

Answer 2

impossible, the universe is 14 billion light-years across.  We can't show evidence of something not existing somewhere in the entire universe.

I can say that there is an invisible pink unicorn standing next to me, what evidence do you have that it doesnt exist?

Answer 3

None. Gray is actually quite possible. If their environment required that they have gray pigment in their skin. Think about it, we are carbon based because our planet has lots of carbon. What if their planet had lots of Boron? They would be entirely different. So basically, I have evidence supporting the possibility of it. Consider that a human, under the condition of lacking sunlight, has grey skin. Hope this helps.

Answer 4

None.  More to the point, what evidence do you have demonstrating that the possibility should be taken seriously?

Answer 5

none.  I also have none for the non-existence of polka-dot aliens, none for the non-existence of five-legged marsupials from Neptune, none for...

Answer 6

none, cause they do exist!

Answer 7

It isn't possible to provide evidence that something doesn't exist.  If it doesn't exist, there is no evidence.  However, I believe that they do exist.  There are just too many people all over the world who have seen and described them independently.  The descriptions are the same, from some school children in Africa to policemen in the US.

Answer 8

Have you ever heard the phrase 'you can't prove a negative'?  Prove you've never robbed a bank, for example.  You'd have to show a video of every second of your life, and then someone could always claim that it was faked...

Answer 9

Umm...Cause green is coolier?

<(^_^)>

Answer 10

I thought aliens were green. You know, little green men.

Answer 11

None.  

1. The probability of any extraterrestrial aliens being capable of reaching Earth appears to be very low.

2.  There are oral reports. Is there any independently verified documentation of their existence?  Clear photographs that could not be possibly be cardboard cutouts?  Dates, times, locations?  Identified photographers?  

3.  Some people will believe anything.  When a US journalist Dave Barry wrote of the danger of "giblet snakes" in uncooked turkeys, some people took it seriously.

Answer 12

your question doesn't make sense.

if they don't exist, there wouldn't be any proof since they didn't leave anything behind.

right now, we don't have ANY evidence they DO exist.... only statements from people. statements CAN be fabricated.

photos don't count cause they CAN be manipulated and altered very easily.

Answer 13

Non-sensical.  

How can you prove that something doesn't exist?  Instead, prove that it exists.

Answer 14

The goobers who originally claimed Grey aliens existed insisted that they come from the Pleidaes.

The Pleidaes have only recently formed, and are far too young to have developed pond scum, much less advanced super-aliens.

That's a pretty good start on proving that it's bologna.  UFO loonies should also learn that having the aliens say that they come from places with obviouly human-derived names just makes their fakery more obvious.

Answer 15

illogical.

no proof is necessary. if you think otherwise, the onus of proof is on you.
