well our universe is big very very big!!!so there is a possibility of other life forms !!!so why are there some people who still dont believe aliens exist?????

because it is highly unlikely the closest planet which has a bit of chance to house a living species is at least 20 lightyears away a lightyear is 300.000 km/s and that for a full year

i belive in aliens but if they are transformars i like them very much i watch their every episode never missed one.

if they exist also we cant find them as they will be very fast where we cant reach also..

Its quite unlikely aliens could live in our galaxy. Other animals or something I might belief but the green skinned humans who make weird noises...I don't think so

i also think sometime can we get a chance to go to the universe and see it.

Well, there are aliens, if we consider ourselves as aliens. Besides us though, I doubt that unless there is another planet with running, clean water and trees. =)

If our universe was the size of googol, there would definitely be more life forms. But it's very unlikely.

I believe that there are definitely other life forms other than the life forms of this Earth. Like for example there are other beings like angels, jinns, demons, etc.

I don't believe in aliens or any other life forms yet. me myself haven't seen any aliens but i saw some vidoe who saw aliens or maybe its edited

They probably do exist, but we really cant put our own biased opinions on it. Yeah, the universe expands perpetually, but what are the chances in finding a planet the can give the exact living requirements a civilization needs. Or maybe what we found to be harmful to us is perfect another species, and what we need to survive kills any other type of species. Its just how things are, so we just may never know

I belive i n aliens

probably they may exist and can see us but not we as their technology may be far more developed!!

There's no life on any planet apart from earth.. You need water on a planet for life to thrive.. Too close to the sun and the water dries up and too far away from the sun and the water freezes so our planet is in just the right position for it to have life. :)

Well as far as i know which is very little there isnt any other life forms, except for zombies! Just kidding there isnt any as far as i know
