That Rosetta’s Comet 67P contains ingredients for life, or perhaps basic organic molecules, is very fascinating.
Also that chemistry could work in such cold environment as in the Kuiper belt.
It's only about 50 Kelvin out there.

I'm beginning to think the question is where doesn't the chemistry of life work?

The existence of God cannot be neither proven nor unproven. It is a matter of faith. Abdus Salam was both a great scientist and a man of faith. To say that he believed in "fairy tales" is simply stupid.
Tullio

Stephen Hawking would disagree with you...
;)

except the Big bang DIDN'T come form 0...or from nothing! ;)

And your proof is?

even Big bang challenged: http://www.nature.com/news/big-bang-finding-challenged-1.15352

in summary:
there was sthg, from what Universe was created...primordial soup!
even if there was just a gravitational wave...it sthg, as a force...not nothing, not zero...but some Energy!
;)

All forms of proselytizing are annoying for the other side. "Folklore" is a better word than "fairy tales"--you can find the same Bible stories in the Dead Sea scrolls which predate Christian writings by a few hundred years. Several years ago there was a very nice exhibit of these in Pittsburg Pennsylvania at the Carnegie Museum.

I am still trying to prove how it is possible for Adam and Eve to have had grand children--perhaps a nasty form of incest going on a long time ago.

Perhaps this discussion should be carried out more courteously in some other thread.

read the Genesis again...they took wives & husbands from tribes of savages, probably Cromagnogns or some other form of advanced primate...diluting the genome into more human form we have now!

& yes, incest is also written in Genesis, as a warning whet not to do...
;)

Life will happen--and evolve

yes, but why?

it's in nature thing to have maximum disorder of things in whole Universe...so why organize a Life in a more complex way? As opposed to maximum disorder of the Universe...

maybe Life or Love of Life is the strongest force in Universe...but we don't know anything about it - yet... ;)

Hawking, whom I respect, is not always right. He denied the existence of the Higgs Boson. I never mix religion and science.

I can see how it can be confusing sometimes...but they can exist in same part...spirituality & science, together!

Life as opposed to "maximum of disorder & minimum of energy"...
Love as opposed to coldness of nature...

Or like one Panonian sailor says:
"Or are we just here as a balance to the Stars..."

Yes, and Graham Greene wrote "should we feel pity also for the stars, if we reach the heart of the matter?".

So let me see:

Adam was not the first Man or
Beastiality was practiced in the Garden of Eden

I do prefer the talking snake in the Jungle book or the Mowgli stories.

What does the fossil record say about this--we do have Neanderthal DNA mixed in with Homo Habilis DNA. When did these species exist. Dinosaurs were here 250,000,000 years ago man was not--kind of blows away the 7 day theory.

It looks like the Moon got its water from asteroids and not from comets. See Nature Communications of 01 June.

Small asteroid is Earth’s constant companion

Researchers’ calculations indicate 2016 HO3 has been a stable quasi-satellite of Earth for almost a century.

Very interesting indeed, thanx for the link, Lynn :) I do wonder if the laws of Kepler still apply in a case like this.

NASA to Map the Surface of an Asteroid


NASA’s OSIRIS-REx spacecraft will launch September 2016 and travel to a near-Earth asteroid known as Bennu to harvest a sample of surface material and return it to Earth for study. The science team will be looking for something special. Ideally, the sample will come from a region in which the building blocks of life may be found.

To identify these regions on Bennu, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) team equipped the spacecraft with an instrument that will measure the spectral signatures of Bennu’s mineralogical and molecular components.

Less than one chance in 40,000 that Bennu will strike the Earth. 'Killer Asteroid', as the author of the YouTube video calls it, may be a little strong.

That's far better odds than the Lotto and look how the mathematically challenged dump their money on that!

Over a month of increased meteor showers starting tonite. But better viewed from the southern hemisphere.

More on Bennu. There was a science channel special about Bennu.

Asteroid strike could cause 'immense suffering'

A huge asteroid hurtling through space at 63,000mph could one day hit Earth causing "immense suffering and death", astronomers say.

The space rock was discovered in 1999 and is likely to blast in between the Earth and the moon in 2135 - a little too close for comfort.

But on a return trip later in the century, it is estimated the asteroid known as 101955 Bennu could actually strike our planet.

Dante Lauretta, the NASA expert in charge of a new mission to analyse the asteroid, said: "That 2135 fly-by is going to tweak Bennu's orbit, potentially putting it on course for the Earth later that century."
