The universe is huge and constantly expanding, and so, many things are happening all at once, so maybe a species just went extinct somewhere, a star exploded, or something else. It is hard to say if there are aliens or we are truly alone. There are many theories, and researches going on about this so if you'd like you can go read a few and get more thoughts on this topic, because until there is a definite answer all we have are theories, unfortunately.
Well assuming there are other intelligent living creatures in the universe, they would refer to other intelligent living creatures in the universe (which can be us) as a word in their language that has the same meaning as aliens. So, yes, for other intelligent living creatures in the universe. But that doesn't mean if we didn't live on a planet we wouldn't be aliens. Because we would still be other intelligent living creatures in the universe for other intelligent living creatures in the universe. And yes, I used copy/paste for other intelligent living creatures in the universe. :) By the way, you refer to humans as "them". Doesn't that make you and alien for us? :P
i believe in aliens because their is billions of planets in the universe that their could be aliens on a planet
They are creatures from another planet that warred with on another continually, when their spirits arrived on a chunk of their planet, they began wreaking war on the living.
yes some
Aliens do not come to our planet but they are real.
As yet, humanity has found no signs of aliens (or any other life) on Mars, or anywhere else in the universe.
yes there are many of them on mars and in the future i think they will visit our planet ('Earth')
I never been in another planet but I assure you that aliens life is completely different than us....
we are aliens too ^_^ ,, because aliens live on other planets,, we live on our planet,, if we call those other creatures on other planets an "alien" ,,,,, we are the same as them,, if we travel to their planet,, they call us back aliens too ^_^,, in their language hahaaha i guess that was the best answer for aliens theory
The Scardox aliens are fictional creatures from the game "Planet Scardox" and are not real. They exist only within the context of the game and do not have a physical presence or life outside of it.
There are no planets of our knowledge that contain living creatures.
No. Because the planet is not suitable the surface is not perfect
