Have Aliens visited earth???

[Pepsi132]

There is a big difference between seeing and sight. Seeing could mean understanding and navigating your surroundings, which is why we say blind people can see, but have no sight, they use other senses to "see". On earth we have all origionated from one life form which developed it's own method of seeing the world by absorbing the light and colors and creating an image of the surroundings in our brain. But the likelihood that an alien has developed THE SAME form of "seeing" is minuscule. They will have made their own version of seeing the world and surroundings. I'm saying all animals need to "see", but they don't need "sight". Whether their form of seeing would be more advanced or less advanced than our sight, we can't know. We think, our hypothesis is that sight is the most advanced form of seeing, but its possible they are more advanced methods by aliens.
Have a good long think about what I am saying before you reply...

Today I was looking to Know Universe and kepler (our space telescope) is looking for exo planets. The siencetist sad that Kepler wil find Alien life between now and 5 years later.

On Earth every creature adapts to the environment. Like birds gets wings to fly in sky so if an other planet has a smoke blanket then the aliens can't see with eyes probably somthing else like smell, then the smell the shape of somthing so can they see to.

I'd think a heat detecting animal, like the Shrieker, is more likely than one that can smell shapes. After all, a creature can have passed a certain tree. But 2 hour later, you can still smell it's been near that tree. Smell is a bad sense unless you combine it with another sense to determine something's still here and where its exact location is.

Correction: OUR sense of smell is bad. We don't use it enough to make perfect use of it. Certain animals such as dogs or cats can use their sense of smell much more effectively than we can. Cats only recognise people through smell. Certain dogs can sniff out something from far far away. Smell is very powerful. And you don't nessecerally need sight with smell. In fact without sight the ability from blind people to smell is much greater.

But you cannot smell shape. For Example:
Plant A has 3 flowers and four leaves, while Plant B, of the same species, has 7 flowers and 9 leaves, but you could not determine the number of leaves, and would have to do some quick math in order to figure out the amount of flowers, a two dimensional vision, at best.
Besides, these re-purposed senses are nowhere near as good as a sense that is used specifically as a means of detecting shape or location: Sight.

Very much true. But smell is not enough to live. You can recognize things with it, but you can't determine their exact position and how they are standing. Its good for finding the general location of something, but not enough. Also, mimicking the smell of something else could cause great damage to the creature you're attracting if there's nothing you have but smell. Imagine you are a blind herbivore. You can't see, hear, or even feel. Then you smell a plant. You go towards it. You nibble at it. Then you get eaten by the apex predator.

What I'm trying to say is, imagine if a predator mimics the smell of one of the most nutritious plants around. Herbivor comes and is sad a couple of seconds later.

I never said you could survive on one sense by the way, nothing can survive on one sense.


But just to say something about this topic, the theory of whether aliens exist or not is unfalsifiable , you CANNOT proove it right OR wrong. So we could go on for thousands of pages of posts, and never ever get to a reasonable answer...

Unless suddenly a UFO appears above the sky and aliens come out.

Not that that's likely to happen. Wait, what's that in the air? HOLY...
*Connection interrupted.*

[Pepsi132]

Out of interest, do you think seeing a UFO in the sky prooves inteligent alien life travelled billions of miles to come here unseen? A UFO sighting is absolute without a doubt NO proof of the existance of alien life...

Technically true.

Unidentified Flying Objects are certainly real, considering a UFO could be a plane in enemy airspace that refuses to identify itself.

However the term UFO has come to mean "alien craft" or "unexplainable flying object" these days, due to media hype over the last couple of decades.

[Pepsi132]

Doesn't it strike you as a coincidence that we only had "UFO encounters" once we had invented rockets. In fact, before we could go to space we never thought of aliens...

Humans have a tendency to create fear with "new monsters", where an area is perhaps unown or newly discovered... We havent fully explored the lake in Scotland... Oh watch out, lochness monster! There's a giant forest (in America?...) stand back... Big foot! Just discovered we could go in space... Aaahh! Aliens...

Monsterology is an actual science of study myths and legends of monsters, they also realised that the more we as humans expanded to new areas, the more monsters are made... I can't explain very well,

But the origin of aliens is simply ( don't know the story completely) but a scientist, an astronomer... Was receiving strange signals from an apparatus, a signal at such a constant rate it was unatural... The scientist had discovered A NEUTRON STAR, for some reason, I don't how the units or apparatus were measured in, but the scientist wrote down LGM, meaning something scientific, I'm not sure what. Then this note was found with the signals, and some idiots thought L.G.M!! That means little green men!! So the concept of little green men visiting earth was widely blown out of proportion, suddenly films were being made... AND COINCIDENTLY people started to see UFOs... Im sure it was a coincidence *cough**cough* *bolprop**cough*

I hope I've proved that, maybe life exists somewhere out there, but little green men in spaceships do NOT exist!!!!!

[DarkGricer]

Not quite true. In the far past, there have been sightings quite similar to UFO abductions. It doesn't necessarily mean there are aliens out there, nor any kind of creature, but they may not have just completely made it up.

[Pepsi132]

How far back do you mean when you say far past? Is this a reliable source? Did they believe it was an alien? Is it documented anywhere?... I'm still definatly not convinced, I need to see proof...

[DarkGricer]

Like in the middle ages and after.
Yes, it's reliable.
No. But they usually involved flashes, just like alien sightings.
If it wasn't, we probably wouldn't know about these sightings.

There are un-explainable sky based "things" going back beyond Egyptian times & many are documented in their carvings.

It is common with ancient civilizations to state that the "thing" they saw wasn't related to themselves or their Gods...which is basically what we say about UFO sightings in the modern age.

A half hour on google will give you a lot of info on alien sightings within ancient civilizations & even the Middle Ages, victorian times, etc.

It's only a very specific type of UFO sighting that has come into fashion over the most recent years...which typically is the "flying saucer" deal, man made toys for the most part.

Sightings of unexplainable "objects" or "artifacts" such as lights & what have you have been going back hundreds, thousands of years.

My belief is that we are the aliens. They are just the future "US" that has developed technology to not only travel through the fabric of space, but time as well. The difference in appearence is a factor of evolution under 0 gravity.

[Pepsi132]

There was always that theory that we created ourselves, and other creatures, and that at some point, we will need to go back in time, to place samples of ourselves and other animals to ensure the balance of space and time -_-

Unfortunalty, time traveling backwards is not possible, time isn't a two way tunnel. You can move forward, by dramatically slowing your own rate of moving through time in relative to the rest of us. Its extremly complicated, its called relativity. There are many theories and possibilities that show we can "go to the future", by aging slower than the rest of world. Confused? Well you might be... Time is distorted when extreme speed comes into consideration.

Well let me give you a small example, it should help you understand the concept. Imagine, two cars are moving towards eachother, and there is a man standing across the street observing. If the cars are moving towards eachother at 50km/h, then to the man across the street, it appears that each car is moving at 50km/h. However to the man inside one of the cars, it apears that he is stationary, and the other car is moving at 100km/h. (its basic perception, if something is moving in the opposite direction as you, it will apear to go much faster.)
Now, the speed of light is around 300,000,000 km/h... nothing can go faster than the speed of light. Pretty damn fast! Now theoretically, imagine both cars were moving at that speed. To the observer across the street, it would appear that both cars are moving at 300,000,000 km/h. But to the man inside one of the cars, what speed does he see the other car moving at? He can't see it as 600,000,000! Nothing is faster than the speed of light. So time gets distorted....
The fact is, the closer something is to the speed of light, the slower time happens in relation to the rest of the world.... If you were someone moving at the speed of light, ignoring the fact you'd be dead; each second for you would be around 5000 seconds for the rest of us... Really complicated... But it even happens slightly at smaller speeds, if you were a pilot, and flew each day, you would be a millisecond younger than you should be.
Then it gets even more complicated, time is also affected by gravity! So being high in the mountains your second lasts longer than the second of someone down by the beach. Of course these differences are so small they are unmeasurable...

So... How did I get to talking about this?... Right... There are many possibilities that we can go to the future, or even beleive it or not, teleport (wormholes). Unfortunatly, you can slow time down as much as you want, but you cant go backwards....
Oh well...
However, there is a theory that we have an infinite parallel universes, and this theory thinks that each parallel, is the exact same, but at different times. So at the moment the is one of the paralel universes with dinosaurs, and another with exactly what you were doing a couple months ago, even one, reading this post, a second before you are reading it. With this theory, you can go "back in time", meaning you switch paralel universes, but if you change anything, it won't affect the future of you "homeland universe".

Unfortunalty, time traveling backwards is not possible,

This is actually false. It is perfectly possible to travel backwards in time.

The transporting of atoms through time & space is possible NOW, we've managed to do it. The point however is that you need a place for them to go/appear. For example:

We build a Time Hub in 2016.
We build a Time Hub in 2051.

We can travel, now, between both. However we can't go further back than 2016 or further forward than 2051.

Question is, after we build the 2016 Time Hub...would we get people from 2051, even though ""we haven't built it yet""? :3

[Pepsi132]

So then there's still the point that we are unable to go back in time, previous to the year 2012... As in, even if next year we built the first machine, it still won't allow us to go previous to 2012, so it is imposible to travel to before 2012...
