TIME explains the tantalizing evidence that suggests life on Earth may have been seeded from other planets

Has to be a discussion here.
People bang on about life being seeded from elsewhere and how tantalizing it is, all the time. It just moves the question to another location that is far away, and can’t currently be studied, and doesn’t really answer anything…

That’s perfectly true, but life on earth might have originated from elsewhere. Thus, the questions: “How did life start?” and “How did life on earth start?” are really two different questions that might have two different answers.
I’m not a believer of panspermia, so I won’t attempt to argue in favour of it.
I agree that life on earth might have originated elsewhere.
The thing is that its a hypothesis with no explanatory power. It doesn’t make any explanation for life on earth easier: it is just an unnecessary complication.
So I don’t see the appeal or excitement for this particular idea.

There seems to be a fair bit of agreeance here on that.
Yes.
Pity there aren’t more loonies here.

Conspiracy talk show host Alex Jones, increasingly a favorite of conservative media for his extremely vocal support of gun rights, outed himself Tuesday as a tornado truther by telling a caller on his show, “Of course there’s weather weapons stuff going on.”
Jones, a longtime proponent of the idea that the U.S. government can manipulate and even produce weather systems like tornadoes and hurricanes, went on to say that if people saw helicopters or small aircraft in the area, then “you better bet your bottom dollar they did this.”
“But, who knows if they did?” he asked. “You know, that’s the thing. We don’t know.”

He sounds like a brianbursted. I bet he curses the weathermen for not getting the forecast accurate for his neck of the woods.

> life on earth might have originated from elsewhere.
Actually, I disagree. If life originated elsewhere then when it landed on Earth it would have had to have found pre-prepared food of exactly the right type to support it. So the conditions on Earth must have been the same as those in the place where the life first originated. So if life originated elsewhere then it immediately follows that that life could also have originated on Earth.
All other possibilities have vanishingly small probability. Consider how difficult it would be for a living organism to survive two collisions each with a velocity in excess of 5 km/s, each with the living thing at ground zero in each explosion greatly exceeding 100 kT of TNT, as well as surviving tens of millions of years in vacuum subject to radiation from solar flares and cosmic rays.

And it would presumably have to be an ecosystem, not just an isolated organism.

But just because life could have originated on earth, it doesn’t mean that life did originate on earth.
There seems to be an overwhelming preference for a good theory than the facts.

Facts require investigation. For a subject with so many questions it is hardly surprising that people settle for an educated guess. Settling for anything but hard data doesn’t seem overly scientific to my mind though.
