Is abiogenesis still occuring?

| Hopefully this'll be an interesting discussion. So how did life start? The preeminent theory is the primordial soup of organic compounds. If that is true, shouldn't life be constantly sprouting? I don't see it happening which leads me to believe life was somehow seeded onto the planet. |

Lets get one thing straight; abiogenesis is a chemical evolution right? This is happening 24/7 due to cosmic rays hitting the earth. A chemical evolution of the atmosphere on the earth; which further causes particles to become ions to form in the upper levels of the atmosphere; from there these ionized particles are capable of avalanching towards earth creating plasma or lightning bolts.
After a lightning bolt fuse particles together; and there are multiple strikes on one path; maybe two depending on the branching of the step structure.
http://en.wikipedia.org/wiki/Miller_experiment
Past that new particles are being created daily by lightning bolts hitting the earth; On an atomic scale new molecules and particles are formed daily.
Think of a liquid which is capable of growing crystals which has perpetual motion of particles at 10^13 collisions a second. Given an extend amount of time on earth crystals were capable of growing out of a primordial soup. Crystals are arranged in the lowest energy states, so with a bunch of time and trial and error of having particles collide with the structure crystals form. Crystals are not biological, but they are new chemical structures which form.
To try and even being say biological life is gonna be chemically evolving is gonna take extended amounts of time; unless you look at how humans are genetically engineering mice to glow in the dark; or using vaccines to cure cancer.
So it just takes time for abiogenesis to take place. In other words Chemicals evolve over time; with out time there is just a chemical; nothing takes place;

Horizontal gene transfer (HGT)
http://en.wikipedia.org/wiki/Horizontal_gene_transfer
Horizontal gene transfer (HGT), also Lateral gene transfer (LGT), is any process in which an organism incorporates genetic material from another organism without being the offspring of that organism.
Right there we have abiogenesis based upon the building blocks of previous events.
Past that earth also got impregnated by lots of metaphorical sperm aka asteroids and meteorites. They don't call it mother earth with out reason. |

1. It took millions of years for multi-organ creatures to appear. Man has only existed for a fraction of this time, meaning that for new life to 'appear' and be observed, we would most likely need to be around a lot longer.
2. Any 'new life' would probably appear somewhere remote where it would have a chance to survive, unfettered by man, thus being unobserved.
3. Who's to say that new life hasn't already sprouted? Many new species are still being discovered, and it may be the case that some species are relatively 'young' compared to us.
4. Conditions on Earth were a lot different millions of years ago. There was more oxygen in the air and it was warmer. This was more conducive to new life: "Towards the end of the Carboniferous era (about 300 million years ago) atmospheric O2 levels reached a maximum of 35% by volume, which may have contributed to the large size of insects and amphibians at this time." |

| I'm just thinking that if life spontaneously sprouted once, it should sprout multiple times, in locations such as Yellowstone or underwater volcano vents. I would think this would be something scientists would be trying to observe in nature. But then again, if it happens, it's on an extremely small scale...:( |

| Conditions today aren't similar to the ones when life began on earth. We were a big rock covered in puddles of burning hot lava & acids 4 billion years ago with lightning striking everywhere all the time. Those are the conditions when the first amino acids formed and they were much more extreme than Yellowstone park, so I really doubt new life is being formed today. We have created amino acids from non-living matter in laboratories though (by duplicating early earth conditions)..but we haven't successfully made a stable form that could evolve into something else..yet. |

| Aliens came here looking for something and obviously didn't find it. Their skin cells remained here and changed the environment forever. |

What if it does but it's immediately eaten by a bigger species? |
