There are many potential answers offered by many people.
Common answers include:
* they want to hybridize with humans and thereby extend their scope, and possibly extend their diminishing biological capacity
* they want to feed off human energies (such as emotion)
* they want to help humans develop and eventually join the many other species that, presumably, are active in our galaxy (and perhaps beyond)
* they (the aliens) are not extraterrestrials but are a plot by some covert human group that is using advanced technologies to intentionally simulate alien abduction in an effort to strike fear into humans and thereby bring about popular support for some military force
* they want the Natural Resources of Earth
* they see the Earth as a zoo and don't want humans to destroy it
Aliens want to know more about us, so they make objects that are known as UFO's(Unidentified Flying Object) to come closer to us. They belive, that we have the DNA, Bacteria, and Blood to help them in a way. DNA can be put in the alien body, and aliens could know about our attitude, likes, and other stuff like that. Bacteria, could help them with there life-span ( which means that they could live longer). Blood is very useful for themselves. Think of a soda that we drink often, it just makes you go to the bathroom, right? But what if that soda has something to do with growth? Well, aliens don't drink it, but they use it to "fertilize". Aliens could drink it and produce more aliens. But they mostly want to study how the human body works, so things called alien aboductions. They do that because that's the only way to pick us up.
Aliens are waiting for us to mine all the precious stones and metals. They dont want to confront until they take order. Therefore we should start nuclear engines or construct their power of the pyramids from crystals. Just any type of energy no matter the price meaning nuclear solar and or water powered. All in the while learning to detect them. Trying to find out there meaning.
If there actually are aliens, they probably want the same things we want... eat, drink, reproduce, survive.
you dont want to know
Wherever they want. They're aliens, for the Queen Mother's sake!
Yes there will be and I want to see it
No, Aliens are not involved in this movie Did you see this movie? Of course aliens are involved in this movie . . . I don't want to throw the end, But yes aliens appear complete with space ship!
because they are mean and want to capture everywhere.
Well if you want to talk to aliens like in a movie, you will have to write a script or story yourself. Then we will all know how you talk to aliens.
It doesn't matter whether they're illegal aliens: you can evict anyone you want to for good cause.
he should
It is a cold planet. Aliens would have to adapt but could live there. It is -125 to 23 ° Fahrenheit. If there were aliens, which there might be, they might want to buy it because you would be able to jump 3 times as high on Mars as you can on Earth. I would want to buy it, but I would pack WARM clothes. Lolz.
Many do, many don't. Some fear the idea that there may be aliens. Some would look forward to meeting them.
Although there are many reports about aliens from outer space, we have no definite, confirmed contact with any such aliens, and therefore it would be impossible to say whether aliens would prove to be useful or destructive, if we actually were to encounter them. We will find out when and if we meet them.
aliens don't have babies i really know that a alien cant have a baby. All i want to do when i grow up is study the stars but i know aliens cant have babies because i already study aliens and the stars.
