That's a possibility. The angels struck them all blind so they couldn't see the asteroid coming. That could be a new movie. sodomaurus Rex or Joyassic Park.

I doubt everything got wiped out.
Doubt?  We're discussing the kt boundary, and kt exinction event, are we not?  You might have missed the word -nearly-, above.

IDK, if they could, I don't think that it could really be described as being easy. The urey miller experiment, for example, didn't create life - and what we -do- know of the early conditions has told us that some of the parameters of that experiment were woefully wrong. It;s a popular experiment to point to not because it explains the origins of life, but because it answers any objections as to the impossibility of a natural origin.

I am the Infantry. I am my country’s strength in war, her deterrent in peace. I am the heart of the fight… wherever, whenever. I carry America’s faith and honor against her enemies. I am the Queen of Battle. I am what my country expects me to be, the best trained Soldier in the world. In the race for victory, I am swift, determined, and courageous, armed with a fierce will to win. Never will I fail my country’s trust. Always I fight on…through the foe, to the objective, to triumph overall. If necessary, I will fight to my death. By my steadfast courage, I have won more than 200 years of freedom. I yield not to weakness, to hunger, to cowardice, to fatigue, to superior odds, For I am mentally tough, physically strong, and morally straight. I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!

Yes, you did say "nearly," didn't you. Touché.

Vorlon just turned me on to Miller-Urey. I'd have to read beyond what Wikipedia has to say about it to discuss what their experiment did and did not do.

Quote:Scientists finish a 53-year-old classic experiment on the origins of life

Quote:Using modern techniques, around a billion times more sensitive than those Miller would have used, Parker identified 23 different amino acids in the vials, far more than the five that Miller had originally described. Seven of these contained sulphur, which is either a first for science or old news, depending on how you look at it. Other scientists have since produced sulphurous amino acids in similar experiments, including Carl Sagan. But unbeknownst to all of them, Miller had beaten them to it by several years.

That's nice, except it is now generally accepted that Miller and Urey's notion of the content of the primordial earth atmosphere was all wrong.  So Miller Urey shows some steps in creation of amino acid can be achieved in a simple laboratory experiment that uses conditions unlike those that actually prevailed on earth at the origin of life.  That's it.  It didn't offer insight into how by far the most important and poorly understood step, which is how the right amino acids are concentrated and encouraged to react in thermal dynamically plausible ways that wouldn't blow the whole thing apart, can be achieved.  So It's actual value in replicating any step in origin of life is much overstated and not remotely as high as once thought.

People should really caveat Miller Urey if they wanted to cite Miller Urey in arguing the process of origin of life is understood.
