	Extraterrestrial life - Wikipedia, the free encyclopedia
		An alternative hypothesis, held by a minority, is panspermia, which suggests that life in the universe could have stemmed from a smaller number of points of origin, and then spread across the universe, from habitable planet to habitable planet.
		Extraterrestrial life forms, especially intelligent ones, are often referred to in popular culture as aliens or ETs.
		Belief in extraterrestrial life may have been present in ancient Egypt, Babylon, and Sumer, although in these societies, cosmology was fundamentally supernatural and the notion of aliens is difficult to distinguish from that of gods, demons, and such.

	Invitation to ETI: Intelligent Life in the Universe: What Role Will It Play in Our Future?
		The fundamental importance of intelligent life in the universe can be confirmed by some of the thought-provoking mental exercises in chapter 2.
		Intelligent life forms that are destructively aggressive and irresponsible will usually eliminate themselves or revert back to primitive conditions before they achieve interstellar communication or travel (Harrison, 198l).
		Intelligent life will have countless billions of years to advance and change before there is any need to adjust to the various stages of the "end" of the physical universe.

	SPACE.com -- Alien Intelligence Depends on Time Needed to Grow Brains
		Intelligent life -- which we broadly define as human civilization -- didn't develop until a few tens of thousands of years ago.
		The paleontologist Peter Ward and the astronomer Donald Brownlee expressed this belief in their book, "Rare Earth: Why Complex Life is Uncommon in the Universe." Intelligent life on Earth, they say, is due to a long chain of events that greatly relied on happenstance.
		Many of the factors that went into the development of life on Earth remain a puzzle to us, so there may be many other characteristics of a planet, or even a solar system, that affect the development of intelligence.

		In particular, the author scrutinizes what kind of information about extraterrestrial intelligent life can be inferred from our own biological, cultural and scientific evolution and the likely future of mankind.
		The basics of planetary science, astrophysics, and biology are presented in the first section, followed by a description of the conditions in which life has evolved, and where elsewhere in the universe we might find such conditons.
		Part three (the section that I found to be the most fascinating) described the nature of intelligent life and the fate of humanity.

	Is there intelligent life out there?
		Intelligence as used in the phrase "intelligent life" simply means life that is self aware, not bound by nor confined to instinct.
		Intelligence itself is not comparative, either a species or individual has it or it doesn't.
		"Intelligent life" is generally meant to be creatures able to use abstract symbols (as in mathematics)--in combination with a self-aware perspective beyond the here-and-now--in solving problems; creatures capable of building complex tools, especially (but not necessarily) a powered technology.

	IS THERE INTELLIGENT LIFE IN SPACE?
		To suggest that human beings are the only advanced forms of life, or as some people suggest, the only forms of life in the universe, could be considered as arrogance.
		There are billions of stars in the universe, these stars have solar systems, and there is a strong possibility that at least one of the planets may contain intelligent life.
		It may be possible, therefore, that there may be intelligent life in space, but there is no realistic way of contacting them, to be sure.

	Universe Today - Where Does Intelligent Life Come From?
		Empirical research into the fundamentals of life shows that a concoction of well-chosen elements (hydrogen, carbon, oxygen, and nitrogen) exposed to non-ionizing ultraviolet radiation forms amino acids.
		For this reason, life may be an ubiquitous phenomenon simply awaiting only certain favorable conditions to take root and grow into a wide variety of forms.
		Life could be as universal as gravitation - and as personal as an evening alone with a telescope beneath the night sky...

	The Fate of Life in the Universe (Site not responding. Last check: 2007-11-01)
		Yet life thrives on energy and information, and very general scientific arguments hint that only a finite amount of energy and a finite amount of information can be amassed in even an infinite period.
		Among all the scenarios for an eternally expanding universe, the one dominated by the so-called cosmological constant is the bleakest.
		Not only is it unambiguous that life cannot survive eternally in such a universe, but the quality of life will quickly deteriorate as well.

	Is there intelligent life anywhere except on Earth? - GameBanshee Forums
		These life forms might however be very different from us, perhaps more different than we can ever imagine.
		On the contrary, I would imagine it would be rather improbably that life forms who have evolved in totally different solar systems than us, would have similar sensory organs to us, and thus communicating in form we can even pick up.
		Any extraterrestrial life able to navigate within earth's proximity would also have the ability to perceive the chaos we wreak upon one another, upon life in general.

	Life on Mars
		At the dawn of the space age, Mars was considered to have an atmosphere about a tenth the density of Earth's, water ice polar caps that waxed and waned with the seasons, and an annual "wave of darkening" that was often interpreted as growing plant life.
		The question of whether life is common or rare in the universe has deep philosophical implications.
		But if life also arose on Mars, this would show that those mechanisms operated not just once, but twice, arguing that life may well be common elsewhere.

	Professor Stephen Hawking
		But then most forms of life, ourselves included, are parasites, in that they feed off and depend for their survival on other forms of life.
		If this figure is correct, it would mean that intelligent life on Earth has developed only because of the lucky chance that there have been no major collisions in the last 70 million years.
		A third possibility is that there is a reasonable probability for life to form, and to evolve to intelligent beings, in the external transmission phase.

	Probability of Life-Support Planets for Extraterrestrials & SETI Success
		Of the 500,000,000,000 galaxies in the universe, 10% are suitable for life in regard to galaxy-cluster density.
		If the size of the galactic central bulge is too large, the radiation from the bulge region would kill life on a candidate life-support planet in one of the spiral arms.
		The parent star must produce a host planet with a carbon-to-oxygen ratio which is suitable to produce the various building blocks of life, without producing a state of lethal amounts of oxygen or too much carbon in the environment.

	Extinctions and Intelligent Life (Site not responding. Last check: 2007-11-01)
		There are countless ways in which life could have evolved but all the time it is restricted by the presence of other organisms.
		After the sixth extinction the state of the biosphere was correct to spawn a life form that was intelligent.
		There must have been potential for intelligence all along and each extinction removed a set of species - sometimes removing those who did not have potential yet suppressed it (such as the Dinosaurs) and sometimes removing species that would have evolved to become intelligent.

	Apologetics Press - Is There Intelligent Life in Outer Space?
		But, while acknowledging the impossibility of the accidental formation of life here on the Earth, he refuses to accept the idea of an intelligent Creator, and instead opts for “directed panspermia”—the idea that life was “planted” on the Earth by intelligent beings from outer space.
		Whether there is intelligent life in outer space or not does not answer the basic question of where that life, or life on Earth, originated.
		In modern form, the idea assumes that, in the absence of evidence to the contrary, conditions favorable to the emergence of life and intelligence as they exist here on earth are present abundantly in the universe.

	Why Intelligent Life Needs Giant Planets by Ken Croswell
		If the solar system had not contained Jupiter and Saturn, intelligent life might never have arisen on Earth, according to a planetary scientist in the U.S. Without the two largest planets, the solar system would be full of deadly comets striking the Earth so frequently that they would impede the development of advanced life forms.
		Jupiter and Saturn are gas giants, consisting of a rocky core surrounded by a thick atmosphere of hydrogen and helium.
		On such a hostile world, says Wetherill, advanced forms of life might not have time to evolve before a cometary collision disrupted the environment, causing their extinction.
