Do ET's exist?

[davidpt40]

Of course they exist.  Earth isnt so special.  

God does Exist..

If God exists, he doesn't take an active role in life.

[Thrawn]

If aliens exist then they don't take an active role in life.

"It would be very egotistical for us to believe "

Oh okay, because it's EGOTISTICAL for one believe that aliens don't exist then aliens exist??

Beautiful logic there.  LOL  


Have yet to here any of you alien thumpers bring any proff of the existance of aliens.  Don't forget your tin foil hats!



Fantastic how the science crowd has no problems believing in aliens that have in no way been proven to exist...but God?  Well, hells no!

At least be consistant.

Well i double that and challenge you to prove that aliens dont exist

Before I believe life exists elsewhere, someone needs to prove to me that it exists here. How do I know I even exist? This is all some crazy nightmare

Nah, just a recovering Catholic, methinks.  

[Sandman]

Where are they?

It's an interesting read...

FWIW... I do believe that there has to be ET's. I just don't think they've ever been here and "Taken" is a crock of toejame. Can't believe anyone (or anything) would travel this far simply to abduct George and Martha from their Rambler.

ETIS -- extraterrestrial intelligent species

Operational definition of intelligent is "capable of communicating via radio"

Probability of finding ETIS -- 2 schools of thought

Cosmological principle -- makes the assumption of mediocrity. We live in an average "neighborhood" in the universe. There is nothing special about our location or time in history or conditions that make life possible. Therefore, one would expect to find similar conditions (and life) elsewhere in the universe.

Anthropic principle -- assumes that we exist because of very special conditions in our "neighborhood." Therefore, what we observe in our part of space is not typical of the universe as a whole, and so we shouldn't expect to find life elsewhere.

Note that both of these principles implicitly assume that ETIS would have certain similarities to us. Removing that assumption complicates these arguments somewhat.

Drake Equation (aka Greenbank Equation)
Developed by Frank Drake (at the Greenbank Observatory) in the 1960's
Tool for examining effects of various assumptions on the estimate of number of ETIS in our galaxy (but it can be applied to any part of the universe)
N = R� P� E� L� I� C� T

[numbers in brackets below indicate permitted values to use in the equation]

N = number of ETIS in our galaxy

R = rate of star formation [number/year]

Our galaxy (Milky Way) is about 10 billion yrs old and contains about 100 billion stars, so R = 10 stars/yr is the standard assumption

P = fraction of stars with planets [0-1]

E = environmental factor = number of planets in a solar system that are ecologically suitable for life [0-?]

L = fraction of planets with suitable environment where life actually did develop [0-1]

I = fraction of inhabited planets where intelligent life-form evolves [0-1]

C = fraction of planets with intelligent life that has developed radio communications [0-1]

T = time [years] that a technically developed civilization survives

Values used in the equation are somewhat subjective.
examples
optimistic outlook
R = 10, P = 1, E = 5, L = 1, I = 0.1, C = 1, T = 5000 yrs

N = 25000 ETIS

conservative outlook
R = 10, P = 1, E = 1, L = 0.1, I = 0.1, C = 0.2, T = 100 yrs

N = 2 ETIS

Do I believe ETs exist? Well, they may exist... but they may not exist in our time.

Our planet and civilization may come to an end someday, and many other civilizations and lifeforms may have suffered a similar fate, or they may not exist yet.

The universe is a huge place, but time... there's enough time in the history of the universe to have witnessed the birth and death of many civilizations.

My guess is that if we ever receive a message from another lifeform in the universe, they will be long extinct before they get our reply.

If they do exist I would suggest that we not try to contact em till we can kick their ass... better than the reverse.

It matters little really..  I have seen nothing that convinces me that they have been here... I have seen no wrecks or bodies or fossils and.... it affects my life not a whit.   I have had several girlfriends that were taken... so long as it had no effect on me I was willing to smile and nod and even believe that the either were or thoght they were.   I also didn't care to talk about it with em since there would be no point.

I do believe and i believe there is more than 1 Race of them.
How can you disreguard all the account from abducties who never met nor new anything about ET's and yet describe the same being and things that happed to them. You think these people are just getting crazy metallic balls stuck in the head by some accident. There is a lot of evidence out the but for the sceptic you'll never believe till your "taken"!

Remeber the FOO FIGHTERS during WW2 both sides saw them and thought they were the other sides secret wepons! And think of all the pilots here an  of you guys see strang thing while up is the sky?
my 2cents  and a statement that yes I believe there out there and have been here!  

Here comes the flames

[Eagler]

it be ignorant and arrogant to think we are the only beings in this vast universe

they view us as we view a mound of fire ants

[Modas]

Of course there are ET's.  Hop into MA since the competition started and look at all the UFO's hovering up there at 35K


Seriously. they exist, haven't been here yet.  They are still waiting to see if we blow ourselves up or not.  No sense in wasting time contacting a species about to to into extinction...
