Because we’re ignorant of - don’t know about - didn’t discovered yet - or couldn’t find empirical proof of “something", doesn’t mean that it doesn’t exist.
Humans were unaware of the existence of the dna molecule up until they discovered them back in 1869. Which is only a bunch full of years in human’s history terms.
Up till then people were pretty ignorant of the workings of genetics, to some extend they still are since not all the “mysteries” of the dna coding have been unlocked yet. At least not officially.
In the specific case of the existence of intelligent life alien to our planet we count only on the limited evidence to our disposal, yet that limited evidence in terms of probability it’s quite staggering when considering the number of stars and the possible number of planets rotating around those stars. And that is just in one galaxy!
It’s ignorant and terribly arrogant to believe that we are the only ones around.
It is said that the creatures that will visit us have better technologies so maybe that's why tey'll come
Cecilia:
Maybe they already came..
bingo!

But we aren't. Humans have always believed in the existance of species on other planets. We've just been a little silly about it. If we can't find them, how do we know they can find us? Maybe there's another planet somewhere looking for other life forms.

There's that ever present theory that aliens brought life to Earth.
Of course that's nice and all, but it would seem more kind if they could visit every once in a while.

Neutron stars can emit pulses of Gamma radiation. Once, a regular pulse of Gamma was detected by scientists working someplace in Manchester and the woman observing it (sometime in the fifties, or sixties, I think) actually wrote "LGM" on a piece of paper and circled it.
LGM standing for 'little green men', of course. Of course, she'd discovered something interesting to do with cosmology and not aliens, but still. I find it a mildly amusing story.
There are aliens. It is egotistical of us to assume that we are the only life in the universe. It also also silly to assume that all aliens would be carbon-based., or even on the same scale as us. They could be microscopic and brilliant. (Ooh, that's a cool idea for a book. Dibs.)
Should life forms exist on that planet, they'd either have to be microspocic, or immensly large.
Well, Earth had bacteria at first, then they evolved into bigger creatures.
I mean much bigger than Earth's. They've got to be. The gravitational pull on that planet is just too much compared with here.
How can you know that? Their forms of life may not be anything similar to earth, perhaps they're composed of something else that can withstand the effects of gravity that our skeletons couldn't.

who knows...
the Earth is only one little planet in an expanding universe...what kind of race should be outside our galaxy?
they might have the same problems and preferences like the humans,and the same fears too...or more.
when our knowdeledge of science and technology reaches a good point we'll try to reach other places outside the Solar System...and they might do so too.
or they're already doin' it.

According to Einstien, all large masses have a large gravitational force as well. Unless the organisms live in a liquid, they'll have to endure the effects of gravity in one way or another. Sure whatever sort of skeletal structure that they may have will most likely be different to ours, but it's really whatever 'muscle' or tissue that they have to have movement with definately have to be greater compared with body mass, to our bodies, otherwise obviously, they'd get crushed. Another reason it could be potentially dangerous to visit another planet with a larger gravitational force, right there.

Course you have a similar the problem of lower gravity fields. If we were to colonise on Mars or whatever, the gravity field is much lower there. This would cause the bones to thin, muscles to thin etc to deal with the sudden change. Then, when you return to a higher gravity planet (like Earth), you'll have diseases like brittle bones, maybe causing fractures and breaks.

But that's why astronauts excersice in their space ships, that's what the excercise bicycles are for. There is no way to know the effect of more gravity on a person unless you visit the planet. (Or walk around with stacks of bricks taped onto your head. But still, you can never exactl tell.)

Hey! I just realized. If even we managed to get contact with beings from another planet, there would be a huge language barrier.
Innerestin' fact there, I thought it had to do with ye olde Hollywood.
