A new paper by a Japanese researcher says that microscopic forms of alien life from other planets outside of our solar system may hitch a ride to earth on particles of space dust. According to the paper, even if these life forms don't survive the trip across the cosmos, researchers should still be able to find ancient fossils, or possibly DNA fragments from these particles of space dust, if there is life on the planets from which they come...
When space bodies like comets and meteors collide with planets, they are often powerful enough to eject some of that planet's material into the void of space. Therefore, the theory goes, if there are microscopic life forms within these particles of space dust and they end up traveling across the cosmos to reach earth, those microscopic organisms could still be there.
Of course, the vacuum of space and the potentially millions of years these types of particles would take to get from any life-harboring planet to earth means that the chances of any of these life forms surviving the journey are effectively nil, at least to our understanding of life. However, the signs of this alien life should still remain in either fossilized form or as small fragments of life frozen for the long journey by the sub-freezing temperatures of deep space...
Although there is no easy way to count the number of particles of dust in space that come from planets outside of our solar system, Totani's models suggest that this number could be much larger than you think. In fact, he calculates that a surprisingly large number of particles of extrasolar space dust from exoplanets could enter our atmosphere on a regular basis.

Chemical reactions on the early Earth may have formed its ocean
Conditions that favor water may be common in the formation of rocky planets.

Ashes to ashes, dust to dust.
As an young adolescent I once asked a brainy college student studying science “Is the so called dust in space a special type? Cosmic dust or something?”
“No, it’s just dust like dust on earth.”
To me that was important because it linked the Bible to the reaches of outer space.
Genesis 2:7
God formed man from the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Space farts may have life.
Alien dandruff,alien pollen, alien car hair...
Many scientists have posited that life on earth was brought here by comet collisions with earth.
We are all stardust.

We are stardust, we are golden
We are billion-year-old carbon
And we’ve got to get ourselves

Just like the dust of the earth? Well if the cosmic rays have been blasting earth dust unhindered....maybe...Earth’s magnetic field protects Earth’s life from cosmic rays and atmospheric stripping solar wind...no protection for dust particles out there...
Lots of “should”, “could”, “might”, “if”, “possibly”, in the text....if they catch these dust particles in orbit around earth, how would the know it wasn’t earth dust kicked up by meteor strikes on this planet....?
If I want to speculate...how about this one...
Earth might be already populated by extrasolar life...if the alien lifeforms can shapeshift we would never know unless we look for it. Send me grant money so I can “study” this intriguing possibility. I’m gonna retire one year after I get the money and spend all the money on wine, and women. Kiss off the song.
...ya well that lake over there could contain fish!!
Probably, I think I learned that in, uh, school...
So could the dust bunnies under my sofa, but that doesn’t mean aliens live under there (although there is that possibility).
The rest of the "JimKnowsDonors" keyword, thanks ya prick:
Pull my finger.
Oh, there’s alien life under there, what do you think moves the dust bunnies around? ;^)
Possibly, of course, all space farts come from Uranus.

I can’t believe no one had plucked that low-hanging fruit.
