“If true, the stirring provided by migrating planets may have been essential to bringing those asteroids,” the astronomers stated in a press release. “This raises the question of whether an Earth-like exoplanet would also require a rain of asteroids to bring water and make it habitable. If so, then Earth-like worlds might be rarer than we thought.”
To take this example further, the researchers found that the asteroid belt comes from a mix of locations around the solar system. Well, a model the astronomers cite shows that Jupiter once migrated much closer to the sun, basically at the same distance as where Mars is now.

May be of interest for catastrophism....
Ever wonder how those watery asteroids formed in the first place?
Whatever the mechanism, I can’t see why it couldn’t have happened on earth the same way — but I am certainly no scientist!
Some scientists have theorized our own solar system was formed when the shockwave from a nearby supernova injected the nebula that was to become our solar system with some of the matter such as the heavy elements that now make up our planets...
And that shockwave caused our own nebula to collapse and form the Sun, planets, etc...
Just a layman wondering, but could the matter riding that shockwave have also brought lighter elements and compounds such as water?
And then could not that water have borne the elements of life from alien seas, from a destroyed planet, flash frozen as that planet was blasted to bits by its exploding star, surviving in deep freeze to be later seeded into our own young oceans by comets?
I realize we’re talking enormous stretches of time between events...Just pure conjecture here...Extrapolating...Trying to put things together and see a bigger picture...
Nothing here precludes a Creator...Just needs to be woven into our theories of His creation as our understanding of the wonders of His works unfolds...
Thoughts?
There are a number of theories about that.
Yeah, right...and a "model" in the 70s showed us going into an ice age if we didn't stop living, and a "model" in the 90s showed that the planet would be too hot to be habitable by 2015, but the one in the 80s had already told us that two thirds of us would be dead of starvation by then...
The heck with their models!
A few if I may
Hydrogen and oxygen have strong binding attributes via their electrons, and so water would be a natural constituent of a wide range of minerals many of which are incorporated to asteroidal material.
I tend to think life began here.
Perhaps biogenesis is a process repeated elsewhere given the right chemical conditions, and a stroke of Divinity. However, the majority of evidence suggests that here it was a strictly terrestrial event, with comparatively little to suggest that life was carried from elsewhere.
The Sun is likely a second or third generation star as well, given the distribution of heavy elements within the present solar material, none of which could have been produced by the Sun itself. It's doubtful if humans would be the same, or be here at all had many of those nutrients vital to our existence, not been produced by those earlier generations of stars.
