There is no scientific proof that they exist, only a very good statistical probability that they do. If by deep space you mean the place outside of our galaxy, then yes, it is more likely they live there as there are many many galaxies like ours.
But, if there are only 2 or 5 or 1 million civilizations out there, it would be as a grain of sand in a beach in the Greek islands trying to find another grain of sand in a beach in California.
aliens live in space
Space, because it contains all things manifested.That is, of course, if they even exist, which is as yet unproven.
outer space... hahahaha
Well that I know of their might be living organisms that exist on mars, but aliens its possible.
If you mean aliens, then there are for sure some aliens in there. If you mean humans then there are some spacemen in space stations on Earth orbit who keep the space stations working.
The creatures that are believed to live in outer space are often referred to as extraterrestrial or alien beings. These beings are hypothesized to exist on other planets or celestial bodies beyond Earth.
Nope. Just fake ones.
We have not found any aliens yet, so we don't know if they actually exist, and if they do we don't know how they live or the name of there home.
because they might be bad, and destroy us for earth so they can live there
At this time, we aren't sure that aliens even exist. We haven't found life on any planet other than our own. There are countless other planets out there. Surely all the ingredients for life must be on some of them. Life as we know it needs water, oxygen and a limited tempture change. However, life such as we couldn't even dream of may exist by different laws. We haven't even scratched the surface of exploring space yet. Who knows what we may find. We may go to the very edge of space, look out and see another blade of grass. Blows your mind, doesn't it? Aliens don't exist. There's a line in a prayer that says "the heavens is the heavens of God and the land was given to the sons of Adam." Hence, no aliens. So aliens can't live on a planet, as they don't exist. If you're talking about humans, well, that's a good question.
There will not be a hotel on the moon for humans but there would be for aliens. humans cannot live in space.
Since I'm not an alien and I don't live in space I can't answer that. You need to find an alien and put the question to them.
