Under conditions like those of deep undersea hydrothermal vents, chemistry will automatically transform into biochemistry-- i.e., the first stirrings of life. Formation of organometallics is the first step.

It may be that simple or primitive life itself is common across the universe-- but higher lifeforms are not, due to their more stringent requirements in terms of development time, as well as other resources and circumstances. Specifically, worlds highly similar to Earth and its history may be quite rare in space.

Simple lifeforms appear to be virtually an inevitable development anywhere in the Universe where conditions mimic those of the Earth of 4 billion BC.

The phenomena enabling quantum computing
may be the same one responsible for creating the very first living things from non-living molecules in any given evolutionary scenario as well. In other words, life developing from lifelessness may be a given universe-wide, wherever certain minimal environmental conditions are met.

The new book Quantum Evolution by Dr. Johnjoe McFadden observes that the DNA of life imposes order down to the very level of the molecular structure itself. Which means that the essence of life also may reach into the strange realm of quantum mechanics.
"In quantum mechanics, everything that can happen will happen."
The quote above offers profound implications for any system based upon or interacting with the universe on the quantum level. Elementary particles like electrons and photons act as both waves and particles, and when offered a choice of paths take them all simultaneously. Only when they are measured or otherwise interfered with do their wave functions collapse, coalescing into a single particle and its determinate path in our spacetime.
It may be that there are many universes-- parallel realities to our own-- with such multiple personality particles/waves occupying them all simultaneously until forced to choose only one.
Only recently did scientists discover that objects larger than elementary particles could also participate in this strange multi-universe existence. Namely, molecules like fullerenes. The diameter of fullerene molecules is comparable to that of the double helix of DNA, or basic constituent of life itself. Thus, it appears DNA may also be able to inhabit multiple universes simultaneously.
It may be that at least some mutations in life within our reality come about due in some way to the multiversal experiences of our DNA. But if so, how exactly does the DNA slip into and out of the multiversal state? Apparently it would enter the multiverse at times when it is adequately isolated from our own reality, and exit again after it has interacted somehow with the multiverse itself.
The isolated state appears to involve at least at times some sort of desperate condition on the part of the DNA, such as stymied growth or reproduction: perhaps stemming from a shortage of food. The DNA might then go multiversal, sampling many possible genetic combinations until it finds one which will dissolve the roadblock in its native universe, then return to affect the change.
Experiments with bacteria seem to show just such preferential mutations in action-- at least in some cases.
Such preferential mutations would also offer a neat solution to the mathematics that seem to prove the probability of life arising in the universe at random to be nil. Quantum accelerated evolution could be the loophole allowing life to bypass the obstacles suggested by the math.

Water vapor (an essential element to life as we know it) can be found throughout interstellar space-- though it is more common in warmer regions (such as gas clouds where stars are being formed) than colder ones.

Apparently around 250,000,000 BC a bacterium got trapped in salt and went into a form of living suspension, to eventually wake up in 2000 AD, stunning human science.
This finding in 2000 AD regarding an organism named Bacillus permians indicates that at least some bacterial spores, under certain conditions, may be effectively immortal. The process in this instance involved the bacterium in a drop of water becoming trapped within a forming salt crystal (fluid inclusion). The biggest difference so far found between this organism and typical modern bacillus is a slightly thicker cell wall.

Apparently entities such as Bacillus strain 2-9-3 could travel through space within meteorites or crystals. Our nearest neighboring galaxy is some 2.2 million lightyears distant from our own-- but organisms as long lived as this might still survive such a trip, even at speeds far below that of light. Independent verification of this finding is still underway.

Circa mid-2002 it appears virtually certain (95% probability) that life would develop within one billion years on at minimum 33% of those planets in the universe and galaxy which offered conditions suitable for same.

Microbes may pass between planets and even between solar systems riding within meteorites launched from their home worlds by impacts with other bodies.
In our local neighborhood, an alien star system would likely receive one meteorite every one hundred million years from our system.
