The primordial universe had a minuscle quantity of phosphorus, which is highly important for living beings since it’s used in the genome.

“low, but not zero, survival rates”
Less than carbon and oxygen?
Phosphorus is also rare in the modern universe.

“lets replace the reason there’s life on earth with something that relies on EVEN MORE chance.”
tbh i watched the video before you posted it here and i think that the possibility in the video is even less likely than life evolving on earth.
Cant wait for scientists procure some concrete evidence on the origin of life tho instead of speculation
It doesn’t require more improbable events. It increases the time and places abiogenesis could have happened.
This hypotesis explains why life appeared on earth so suddenly. That is the evidence.
True, it would be more likely as there would be more time to do it and there would be more locations for it to form.
what im saying is the whole panspermia thing is horrendously unlikely. Life would have to be on an ateroid, survive for millions if not billions of years, and then miraculously make its way into the solar system, or even into another planets orbit.
With the VAST expanse of the universe, tell me that life making its way here is likely.
Dude the video says all the asteroids in the universe have life. Or a lot of them. Every rocky body was habitable.
Well, it could come from anywhere nearby Earth, and it could be in a tardigrade-like state of hibernation.
Then why isn’t life on every single planet? We haven’t detected it on Mars even tho we sent there so many missions, and it’s a lot more life-friendly than asteroids.
The solar system wasnt even anywhere NEAR existant in the time the universe was “filled with life”, according to the video itself.
Even if there were life on asteroids, it woulda died out by now most likely
Only the ones on earth were able to exit the hibernation.
and how likely is that scenario 
It would need to have the right conditions, not found on Mars
You beat me to it.
It’s more possible than it forming so quickly on Earth, or Humans even existing in the first place.
gotta love a source that says “maybe” and “could have”.
concrete evidence right there, prime source
Wasn’t early Mars more life-friendly? And perhaps Venus too?
100%, if a lot of asteroids have life.
We can only speculate on this subject.
Yes, there may be undiscovered fossils of microbes or multicellular life.
True, but most evidence would of been destroyed in there apocalyptic ends.
so…youre saying only the ones that made it to earth in your scenario were able to exit their hybernation, even though they, in your scenario, evolved to HAVE such hibernation?
Other thing to consider:
DNA has a natural half-life, and after a few million years it would be unusable to any organism.
So how would asteroids travelling for millions of years deliver healthy microbes?
Edit:
" 521 years
A study of DNA extracted from the leg bones of extinct moa birds in New Zealand found that the half-life of DNA is 521 years. So every 1,000 years, 75 per cent of the genetic information is lost. After 6.8 million years, every single base pair is gone." - Google
