Stephen hawkings believes that aliens are likely to be out there and that they are dangerous. He believes that aliens will want our natural resources and may want to take over the planet. I think aliens are already here and have always visited the earth. But then, all aliens are not the same, so he could be right. Aliens that have not yet found us, may have a different plan for earth. What do people here think of this?

I read that one. I always thought that announcing outselves to people with inter-system transportation before we have it ourselves was a bad bet.

But I'm really amused by Hawkings' "scientific" attitude here. There are "almost certainly" aliens. (Based on a sample of ZERO to date). And then going into great depth in what the motivations of these hypothetical aliens are and how they live.
"Nomads with no planets", etc. He basically spins out a bunch of science fiction that would have been dated in the mid fifties and people take it as a scientific pronouncement.

You have a point lin. I guess because Stephen hawking is so famous, that people will just listen to him. The universe being as big as it is, just tells us, that there is likely to be alien life out there. Space crafts or ufos have been seen by pilots and even astronauts. I still believe aliens have always visited us. I don't know why they have not made contact, but I guess earth would be an interesting new world to them. But yes, Stephen hawking saying that aliens are a threat and their intentions is based on very little. If there are aliens that are advanced enough to reach a distant planet, they would have probably found ways to renew their resources and preserve life.

Carl Sagan was the really weird one with this stuff. I saw this thing he did once where he computed the likelihood of there being extraterrestial intelligence.

How many suns, how many would have planets, how many of those would have atmospheres, how many of those could support doughnut shops, whatever. Came up with this "worst case" figure of --you guessed it--billions and billions.

Trouble is, at that time NO other star had been observed to have a planetary system. He was extrapolating from ZERO data. And getting sloppier as he moved out into the characteristics of these planets that there was ZERO proof even existed, much less in number, much less from a finite, counted number of stars.

It's like a guy walking on a white sand beach and noticing a red grain of sand. Then trying to calculate how many more red grains there are. You can't extrapolate from a single point or datum.

But these guys do. Which is great. But a big mistake to call it science.

I recently saw an old twilight zone where two couples and one child were attempting to board a new ship for a new world because theirs was on a path to self-destruction. They were as ordinary as us. At the end, the ship they were hijacking was shaped like a flying saucer and their destination about which they had no knowledge but hope, was Earth.

It is normal to project our own psyche onto some outside life form; we treat each other on this earth with wars and greed over natural resources and borders; why would we expect better from some other life form coming to our earth?

I believe the earth itself as a planet and the many life forms that inhabit this planet are all evolving toward some unknown future. That's as far as my intellect will take me. It is conceivable that the future may, indeed, include travel to other systems with or without different lifeforms.

If there is a master Creator that started the big bang that brought us into this experience, that same Creator may have done the same in other places with different results. My belief in a spiritual aspect to my life and my hope for a soul may just be manifestations of my existence; just as other religions consider non-believers as without value; the same could hold true of other life forms traveling in the universe. We could matter as little as the mistreated cattle we slaughter and the chickens we smash to feed our gluttony cheaply.

Well, if aliens have been visiting us. Then they will probably be able to destroy us. I think they are much more advanced than a search and destroy mentality. Were all guessing here of course. Maybe there aren't any.

There are some interesting theories on aliens. We all could be just an alien experiment. If there are aliens, then why have they not made contact. I believe, there could be no reason to. If they are here, they would be far more advanced in everything. Also, they don't know how us humans will react to them. It may also stop them from doing what they do here, the earth could also be like a tourist destination for them.

Yeah. Well they sure are not showing people they are here. Has the government been keeping the facts closed to the public. Area 51?

Area 51 is a decoy. A government plot to divert attention away from the REAL cover-up in Area 53

Does being alienated count?

COUNT? It's an uninalienable right

I just watched the movie Avatar. A story about us humans that are running out of natural resources need to invade another planet. So to them we are the aliens. Interesting story. Not much about the topic we are talking about, but the movie was so bad. Very bad movie.
