NASA: ‘There’s a Chance’ of Alien Life Out There, But it Hasn’t Visited Earth

New DNA Can't Be Created With-Out Protein
And New Protein Can't Be Created With-Out DNA

And Neither Can Be Spontaneously Created
At ALL

DNA Can't Evolve Itself Into Existence

 

[Vastator]

But there is no evidence of any other strand, or example.

So what? It's just as plausible that dna was persistent and had little no no real competition. There doesn't need to be evidence of another model (even thougheven though one may exist and we wouldn't know it if we saw it). Especially if this poor model was all but eradicated.

Are we to believe that this fertile Eden was a one trick pony,

No, and we have covered that many times already. You simply do not have good reason to insist that to be true, if one says abiogenesis occured here. The only argument for this you have proposed is that other models don't exist here, as far as we know. However, that is easily explained away by selection, and just the type of selection that would cause a dominant, most-persistent model to form in the first place. Therefore, this is just not good evidence or argument for what you are proposing, as it is just as simply, in fact more so, explained another way.

Selection infers competition. There is no evidence of a competitor...

An Eye-Ball Is Not A Strand Of DNA

And An Eye-Ball Didn't Evolve Into An Animal

Selection infers competition

With other extant or future models of life? Not necessarilly. That is a spurious, arbitrary claim by you. The structure of DNA was most certainly selected for, maybe or maybe not at the expense of other extant or future models. The shape of the water molecule is also "selected for". The only "competition" there is other shapes of the water molecule (which can exist, under varying conditions, as they them become "selected for" under those conditions). Stars are "selected for" under the right conditions, and "selected against" in others. There is no need for extant, competing star models to exist and be somehow defeated by the spheroid stars we observe.

A theory I've often considered myself, if I understand you correctly... And if so... If life requires a lock step formation process... And at its most basic form, is always arranged the same way... Then life across the universe, no matter where, or when... Would have had "identical" ancestors. An interesting theory. But one that begs the question... If earth is capable of sustaining life... Or even forming it, as some believe... Why is it not doing so? It seems that periodically this prime life form would keep presenting itself through formation, at various times, and places, through out earths history as conditions change...

 

[Fort Fun Indiana]

So, these mythical alien lifeseeders... I have some questions for them:

1) How did you orchestrate all of the known mass extinction events though such varying methods, and how did you know which animals would come out on top, creating a circuitous, evolutionary path leading to modern humans?

2) A gamma ray burst could eradicate modern humans and could have eradicated one of their ancestral species. Can you really see the future, and know when all gamma Ray bursts will happen throughout the Galaxy?

3) Why do we observe so many superior traits in other animals that could benefit us? I mean, holding one's breath for more than 3 minutes would come in awfully handy. So would being able to eat less, or being able to regenerate fingers.

4) Why are we so goddamned helpess and fragile, on a planet with such varying environments? About 90% of the environments on Earth would kill us, after some time of exposure. But those damn insects get to wander half the planet. No fair.

Exactly what an alien assuming human form would say.....

‘There’s a Chance’ of Alien Life Out There, But it Hasn’t Visited Earth.

Nobody in NASA has a clue if there is life outside Earth.

None of the scientists have any more valid information on that than any other human because right now we only have one data point and that is earth.

Until we get another data point from some place else all we have are jackshit guesses.

But we see here that when conditions are right life is possible. And there are billions of other places too far for us to go see. Hell, we don’t even know what out there with mars. It’s too far from the sun to see that far. Or barely. In other words we don’t even know our own solar system let alone other places.

What if there are living things in Europa? That would be more evidence.

What if life once existed on mars? That would be even more evidence life happens when the conditions are right.

Even if it’s 1 in a billion that means there are hundreds of other worlds with life

We know that conditions are not right with chemical abiogenesis. That was demonstrated in 1953.

Thus, we are left with organic abiogenesis. Yet, life only begats life. Not non-life begats life. However, the atheist scientists keep coming up with ways to get funding.

I.E., the scientists.

And at its most basic form, is always arranged the same way.

That's where you lose me.... I see no good reason to rely on such an assertion. That would merely explain back to us life only as we know it already . It's circular. (I assume, by "same way", you mean the building blocks themselves are the same, all over the universe. Therefore, all are DNA, as there is DNA here.)

If earth is capable of sustaining life... Or even forming it, as some believe... Why is it not doing so?

How do you know it is not? The process to life here likely took millions if not 10s or 100s of millions of years. Much of the organic matter on the planet is currently tied up in biomass, so we should not expect life as we know it to form so readily now as it once did. And any type of nascent life or its primordial constituents would have to displace extant life, which we know is literally everywhere.

It is likely more correct to say life is ALWAYS forming, everywhere it can. But certain things stop it and slow it down, not the least of which could be extant life.

It would not be silly to say that, on another planet, a model similar to DNA may be slowly forming and take a couple billion years to persist and meet a working definition of life. Just as plausible is to think that many times throughout the universe this process was halted almost entirely by cataclysmic events. Your warm friendly star exploding would be no fun for any extant life, or primordial constituents on their way to becoming life.

Interestingly enough, we look at exploded stars everywhere and find exactly what we thought we might find: necessary chemical constituents of life as we know it.

Dawkins isn't funded directly per se, but he makes his bread from book sales, science career as well as television and film appearances. His tv shows and appearances would be funded by those who stand to make money through supporting him. .

All your questions presuppose that the seeding of earth was intentionally orchestrated by a sentient species... I never posited such a notion. Personally I find such a theory unlikely...

They came here and fucked monkeys.

By The Time They Got Here
They Were All So Horribly In-Bred
They Couldn't Help It

I think a scientist figured out how many it would take to prevent inbreeding. I thought the number would have been ten or 40 but I guess you would need over 100 people to prevent inbreeding

Why is it that I lose you there? The only evidence we have supports this...
Why would the existence of life stop the formation of new basic life? Ice exists, yet new ice still forms. There isn't any proof that the existence of a life form renders impossible the formation of new life.

I love me some tardigrades. The best proof we have to date that micro organisms can, and have survived exposure to open space.

Well I was close and it's late or early..

 

[Vastator]

Panspermia to this point is a valid theory worthy of pursuit. All the mechanisms involved in panspermia are demonstrable, and observable. From micro organisms surviving open space travel, to extra planetary material arriving here on earth. Many rocks of Martian origin for instance have been found in earth.
Here's a link. I just pick one at random to give those new to the theory the gist of what panspermia theory entails...

Yes, and great books they are! His "The Selfish Gene" book is an amazing read and revolutionized biology.
