The possibility of life on other planets.. Aliens...

Guybrush · 03-21-2009, 01:41 PM

Human intelligence took a long time to evolve, but it's clearly a very good strategy and should possibly be on other planets as well, so I don't see why you shouldn't find it on other planets.

By the way, if those were bacterias, they were pretty damn huge. But yeah, the truth is people go out of their way to fabricate and decieve people when it comes to this, I don't feel like I can trust any footage I've seen. If there are aliens out there and they wanna contact us, they should just do it and make it a bit more noticeable. Why all this flying around and acting suspicious?

Well i assume that if we had the right technology and found a planet occupied by advanced organisms like ourselves we'd probably stick around for a bit and see what they're all about.. that and get them all jittery...

It's funny how most Christians think it's aburd to believe in life from other planets. And that the common explanation is that UFOs are just illusions from Satan.

Wheres the logic in believing god created all these f*cking planets and only one of them serves any kind of purpose and is able to support life?

And if you're an evolutionist, think about the odds, are we just a fluke? And a pretty great fluke we must be if we live on the only planet among millions, maybe billions, to support intelligent life.

I don't really think most Christians believe that. In my experience it's only the hardcore fundamentalists that think that way.

Yes, it's a known fact that the creation of life on the earth was a great fluke. That's why I'm so skeptical that life could exist on another planet, unless the universe is infinite (which hasn't been proven yet). And if there is any other life, I highly doubt that it's anywhere near enough to our planet to be sending UFOs and the like.

Most people I meet and myself included feel that if life can exist, then it will. If you have a planet where life could potentially exist and it's been like that for a billion of years, that could give life a lot of chances to get going. If you think of it in terms of statistics and use a little imagination, you could come to the conclusion that absence of life on an earthlike planet is much less likely than the presence of life.

As for aliens, I'm just not sure how even smart ones would get here. I'm not saying it's impossible, but let's face it .. they might be very far away. Maybe despite possible advances in technology, space travel over immense distances still won't be feasible.

No, absolutely not, that is something that has neither been proven or disproven.

Origins of Life on Earth - Biology Online

"It is believed that heterotrophs were the first beginnings of life on Earth, inhabiting the sea and absorbing the organic material that was being created by the reactions of Earth at the time (i.e. the creation of amino acids). The building blocks of life created these organisms and also acted as a food source."

I learned in biology last year that the creation of the first amino acids had something to do with lightning hitting some particles, but I'll be damned if I can't remember what the actual experiment to test that theory was (toretorden, any ideas?). Point is, amino acids were pretty lucky, but this planet's perfect conditions is the real fluke.

So what's stopping that "fluke" from happening in other solar systems? When you consider the trillions of stars and planets out there, it is very likely that such a "fluke" could happen again. Also one could assume that all life, if given enough time will evolve to some sort of intelligence.

Yup, you're probably thinking of Stanley Miller and Harold Ureys experiment from the 50s. At the start of the experiment, they had an isolated environment with water, ammonia, methane and hydrogen in and added some heating, cooling and electrical sparks, conditions they thought would have been present on the early earth. At the start of the experiment, all the carbon was in the methane. After running the experiment for a while, evaporating and subsequently cooling water, zapping it etc, a significant portion of that carbon was found in new organic molecules such as amino acids, sugars and lipids proving that such molecules can form from basic, inorganic "ingredients" under such conditions.
