We can speculate on why the 24 closest intelligent planets have not visited Earth the last 200 years. Half of them are not sufficiently more advanced than humans to get here. Of the 12, Two never developed sufficient interest in traveling between the stars. Two made trips to various stars, but not Earth. They had several disasters and decided traveling between the stars was too dangerous. Two have had economic trouble in recent centuries, so star travel has been suspended. Two visited Earth several times in centuries past, but have found more profitable places to visit in recent centuries. Two have visited Earth recently, but the rich and powerful of Earth did a skillful job of casting reasonable doubt about alien visitors Two are presently enroute to Earth and will arrive before the end of this century. Please suggest some other excuses and/or tell why these excuses are not valid. Neil
They've been listening to our radio and television broadcasts for the last century and wisely decided to stay away until we learnt to stop crapping in our own nest.
2 are already here and are just hiding among us as either the descendants of neandertals or mice.
We are dull? Kinda like Cleveland?
(WC Fields joke Clevelanders!!!!!)
Deb, LOL.
Maybe we have poor personal hygiene by alien standards, and their too polite to say anything.
Veng - Definitely the mice, vale Douglas Adams
Before traveling or telephoning to us, they would write to us. It is probable that they have already written some letters, but people on the earth haven't noticed nor replied, and they have no wish to visit us.
Satt's right - maybe they are very polite and don't want to drop in unannounced, but also so shy they don't feel they can make the first move unless we're introduced formally by a third party....
Or they have in fact been here, but turned out to be of a size so disproportional to ours that their entire invasion fleet was accidentally swallowed by Aunt Patty's mongrel dog.
(OK, enough Douglas Adams references already)
Or conversely we are stuck in a piece of lint in their belly buttons.
if they are more advanced than us, they will probably study on us.
In this way they could know what their ancestors might be like or what kind of IQ thier ancestors might have :wink:
What makes you think I'm not already here?
If they've been watching the 'X files' then they probably think that the place is over-run with BEMs and not worth visiting.
In reality the chance that two galactic civilizations would attain the same peak of sophistication and be able to notice each other is minute. Think about it, it was only after WW2 that radio-astronomy started. In the hundreds of millions of years available we've only had 50 to listen out. Why should the lot on the other end be any different?
Why hasn't E.T. visited earth?
What makes you think he hasn't?
I should be cruising down the Extraterrestrial Highway at the very end of this year. If I see anything interesting, I can let ya'll know. Know what, I haven't a clue....
E.T.
E.T has not visted Earth because he is to busy picking up chicks,beer stop,to pick up 39 san Diego fearks,to rent Independense Day,to listen to the art bell,to exploit Dirty Disney lol
He already has....
He phoned home and they came and got him.
He already came, told every people he met that he was an E.T, eventually tried to prove it by hovering above the ground, but people said that Criss Angel could do the same so nobody believed him. Then, he left
It's easy to make fun out of this, and perhaps humour is the only valid response, but Enrico Fermi asked the question "Where is everyone?".
The more we know about the prodigious nature of life on earth and the potential homes for exobiology, it is puzzling that we havnt detected a squeak from looking around the universe.
I think they are there all right, just a very very long way away, and most definitely out there and not here.
The relevant question would be, given some particular density of species with interstellar travel capability, and given the density of potential places to visit (say the solar systems with planets), what would be the mean time between visits to the Earth? If the Earth had been visited by ETs once every 5,000 years, would we necessarily be aware of it?
1. Maybe we are all aliens - life came here extraterrestially and evolved.
2. Maybe life doesn't come here.
3. Maybe life is too small (sub atomic), too large (galactic cluster sized) or too foreign (e.g. a smart cloud or a smart ocean) for us to notice.
4. Maybe the chances of intelligent life existing at all being so remote (about 1 : 10 ^42,000 against) we shouldn't be here at all
5. Maybe we are all just simultations in a big progroam somewhere on some advanced civilisations PC.
