Yes, I think aliens exist but they are not in this earth possibly in the other galaxy

I don't believe there is extra terrestrials... but there could be a possibility if there was a planet that could support life that wasn't earth.

Flyinyoshi360 : If they exist, if not, I don't care. I know they aren't gonna come on earth and attack humans.

I personally haven't had any experiences happen to me but I still do believe that there is something out there. With the huge size of our galaxy alone, not including beyond it, I'm sure there is something living out there. Scientists have even found planets outside of our galaxy that suggest alien life. It's pretty interesting stuff.

This is actually the most recent lesson I have been giving my 8th grade students.

Now, do I think there is any truth to any of the stories about people being abducted, UFO sightings, or governments finding crashed ships? Absolutely not. Do I believe that there has to be somewhere out there that supports life? Yes. I have been teaching astrology for a little while now. Our Milky Way Galaxy contains over 100 billion starts. Many of those have their own planets. Granted, there have been only 3 confirmed planets (aside from Earth) to actually have water in liquid form (which is the medium for life), but we have only been able to observe the smallest fraction of other planets in the whole galaxy. Now, that is just our galaxy. The entire Universe contains billions and billions of other galaxies. The math alone is in favor of the idea that out of all those countless amounts of planets that form the same way the ones in our Solar System did, there has to be at least 1 other that has the right conditions for life.

Now, with that said, I will explain why I don't believe aliens have ever visited Earth. The closest star to our sun is 4.2 light-years away. The fastest our shuttles have ever traveled in space is about 17,000 mph. So it would take 165,776 years just for one of our shuttles to reach the closest star. So unless there these beings are either immortal or can live for hundreds of thousands (or millions depending on how far away they would be), they couldn't live long enough to make the trip. Now, an argument would be what if there were very advanced aliens out there? Possible. But everything in this Universe is bound by the same laws of physics. One of those hurdles is that matter cannot travel the speed of light. If it did, the matter would be to hot and rapid that the quarks would literally go back into the form of pure energy (quarks are what make up protons, electrons, and neutrons). So at that moment, any living thing going that fast would be dead from their physical bodies beings destroyed and turned to pure energy. Now, with the way energy works, it wouldn't just form right back into the spaceship that it was before when it slows down. Energy does not work like that. After it slowed down, you would get quarks again, and they would form into the simplest atom, which is Hydrogen. The entire shuttle and everything in it would be made into pure hydrogen gas.

So since no matter can travel the speed of light, and the farthest planet we have been able to observe is 5,000 light years away (and that one showed no sign of being able to sustain life), the closest there could be any alien planets would be over 5,000 light years away. Even if they were advanced enough to have a ship that could travel as close to the speed of light as possible before being broken down into pure energy, it would still take them OVER 5,000 years to get here. And that is IF they have the technology to travel very close to the speed of light. Otherwise, we are talking a trip that would take millions of years. Again, unless they are immortal or live that long, the trip is just too long for them to reach us. We certainly will not be able to make it that far out.

hackerman : don't worry hackerman, that's just sleep paralysis, I get it too.

I just made a thread on it https://www.vizzed.com/boards/thread.php?id=57802

But when I was younger, I used to think it was some supernatural force as well. Then I did some research and found out about sleep paralysis. Apparently 80% of alien abduction stories have come from people who suffer from sleep paralysis.

You know what, I guess I do. Scientist don't know for sure, but there is life on other planets in other galaxies.. We'll see that in 50 trillion years..

To be honest they could exist and they could not. We can't say for/at the moment that their isn't any other form of life out there some where. Me personally I think there are other forms of life out there, just not in our solar system or galaxy.

I do not think they exist. I think that if they did, they would have already made contact, and we would know about it.

thing1 : I'm pretty sure they have already made contact but the Government has kept it very confidential. 
The Government controls what gets posted in the media so all the people that have had encounters are kept out of the media.
 

I think alliens exist. We can't be the only life in the universe, thats crazy. 

Aliens must exist, it's practically mathematically impossible that Earth is the only planet in the universe (which is virtually infinite) that can sustain life. We may be the only life in this galaxy, but as for the entire universe, no. 

For me, I honestly think aliens don't even exist. They are just a bunch of fairy tales that no one will ever see in real life.
