who thinks that were the only form of life? why haven't the aliens came to earth?

Answer 1

Are you talking "intelligent" form of life? Because, there are plenty forms of life right here on earth. But, if aliens exist, they probably live in a universe too far away for us to have discovered them and them to discover us. Otherwise, yes, we would have been visited by now.

Answer 2

Considering that we've only recently (the past three centuries) discovered the existence of microbial life, what's not to say that to some other form of life, we would appear as mere microbials, yet we don't have the means to deliniate what is beyond our own frame of reference. Some may consider that an explanation of "gods" and "spirits", and that's a possibility of where the unseen events that imply intelligence beyond human could come from.

That's how I would term life beyond our own. As far as the kind of alien life most people talk about, the 'humanoid' creatures such as the 'greys', can't say that it's anything more than a myth and wishful thinking. There may have been visitations, but the chances seem too conveniently aligned with the emergence of our own technology and pop culture interest in Science and Science Fiction.

Popular 19th century atheism promoted the idea that man is the highest form of life in the Universe. That in itself sounds just as absurd, and even a bit pathetic to think that we're the best that this cosmos has put out.

I don't doubt for a minute that there is life in other solar systems under similar conditions as our planet in this solar system, but the chances of us crossing ways with them seem far fetched.

Answer 3

If there were life on another planet out in the universe, which there probably is, given the size of the universe, it does not mean they are more advanced than us, as is always depicted in the movies. However, if there were species capable of travel to other galaxies, why would they want to come to earth? Bill Watterson said it best in Calvin and Hobbes: "Sometimes I think the surest sign of intelligent life in the universe is that none of it has tried to contact us." Humans can't get along with other humans. Humans try to inflate their egos and be the dominate species in all walks of life. If the aliens showed up, humans would feel threatened to the point of attacking them. Or they would try to steal their technology so they could conquer another planet. True, not all humans are like that. But if you look at the media with their capability to promote fear in everything (there are people afraid to buy spinach and peanut butter because of possible e. coli), there are certainly enough.
So why don't the aliens just come in and wipe us out? If not all humans are so attached to violence, it stands to reason that it may be possible for some more advanced race to not be prone to any violence. If the aliens are capable of intergalactic travel, they certainly didn't do it by focusing their technology and science on weapons...they focused on bettering themselves.
In short, we're not worthy of meeting such a species. Not yet. Maybe not ever.

Answer 4

The aliens probably haven't come here because we reside on the end of an outer arm of our spiral galaxy and are probably out of the way for any extraterrestrial visitors. Most aliens, in order to have the technology to explore the galaxy would have to be an older culture and live closer to the center of the galaxy, and thus head toward the center where finding life would be more likely.

Answer 5

Because if the laws of Einstein hold true we are so far away from any possible star giving life to a planet with aliens that if some aliens wanted to visit us in a starship moving at the speed of light they should start and their greatgreatgreat grand children would arrive. The star closest to us : Proxima Alfa Centauri is at 2.5 LIGHTYEARS (the distance the light covers in one earth year) and our present "spaceships" are far from travelling at the speed of light. So we are alone in an immense emptiness.

Answer 6

We do not know either way, if the aliens have come to earth or not.... for instance, as a radical thought, is it not possible that they may have built up capability to travel in a spirit-form keeping their physical body safely at home?

In my view, nothing is impossible in this colossus of universe as vast and varied as it is.... there could be aliens or not.... they might have visited us or not.... they might know of us even without visiting earth or not... just about everything is possible according to me.

In my view, raking our head with these unending possibilities would be idle curiosity... nice to indulge in once in a while, but certainly not meriting any serious consideration.

Answer 7

The aliens have come to earth. There is a park behind my house. Every so often a space ship lands there. I go out and talk to them on occasion. They seem inquisitive and have always been nice to me. They walk around at night and look around. They can see through walls and can see what we are doing.

Answer 8

the nearest star system is a few light years away. so that means if you were travelling at the spead of light thats how long it would take to get here. now, considering light speed is not possible, it would take generations to actually reach earth. plus thats assuming there is life there. any life is probably a few hundred thousand light years away. and if so, you better bring a pillow cause thats a looooooooooonnngggg trip

Answer 9

The probabilities are not on your side, but the skies are sure silent. The only sound SETI has picked up was 72 seconds coming from the deep space...but nothing since 1977. So what are the conclusions, there are no aliensand we are alone....not likely.,

If there are, they may not be advanced enough to contact us, or may be too advanced and they look upon us as ants in an anthill.... Myself, i look forward to 'first contact."

Answer 10

1/ they might have (but unlikely)

2/ the universe is vast and they may not have noticed us tucked away in the not very fashionable wing of an insignificant galaxy

3/ they may not bother
