Author | Topic: Problems with the first life | |||||||||||||||||||||||

The question of ozone layers at the very beginning is unnecessary. Obviously life survived, wether because of the protection of the atmosphere itself (not only ozone interacts with UVB and UVC) or the water wherin the life occurred. It survived. The amazing thing which science accepts but wishes to ignore is that life emerged the moment there was water. And it contained the fantastically complex genome which has been the basis of all further evolution.
This is what science's holy rule that all is a result of random events cannot allow. Mihkel

By definition, there was a first single cell life form. The problem is that it occurred 3.8 billion years ago, coinciding (at least in geological terms) with the existence of water, a prerequsite for any life. This gives far too little time for random events to combine simple amino acids to single cell organisms with the exqusite genome which is the basis of all present day life. And that includes the Cambrian explosion of species 530 million years ago.
You can statistically rule out random events even over the very short span of some tens of millions of years as sufficient. Unless you want to make liars of Crick and Hoyle among many others. Mihkel

I should refer you to the literature on the subject. Suffice it here to refer to the Cambrian explosion of life forms 530 million years ago. For 3.3 billion years, life on Earth was confined to primitive single cell organisms, when suddenly, during an amazingly short period of 5 million years, a plethora of species with jointed limbs, internal digestive organs, eyes, mouths, etc. appeared from nowhere. The genome did not come about through random processes over 5 million years; that is statistically absurd. The genome had been dormant for 3.3 billion years - there is no other rational explanation.

I am deeply gratful for your courtesy. It matters little whether the first living organism came about abruptly or gradually, it was still the first. I think you are neglecting the statistics of random events. Tens of millions of years would be woefully insufficient time to produce a life form from basic amino acids. Consider this little example:
Homo Sapiens is considered to be most closely genetically related to the chimpanzee. The first hominid appeared about 7 million years ago. The most conservative estimates indicate that random mutations of the chimp genome to that of Homo Sapiens would take some 100 million generations or something on the order of a billion years. I am sure that science is desperately trying to explain the seeming anomalies in the process of evolution, for the religion of science is that random processes simply must explain everything. That is perfectly natural - if a little narrow minded and myopic in nature. Mihkel

Calculating the likely time requred for random mutations is no mystery. It is up to you to believe what you want, of course.
As for misunderstanding Crick, let me quote him:"Given the weakness of all theories of terrestrial genesis, directed panspermia should be considered a serious possibility" That is pretty strong stuff from a totally convinced random process believer. Mihkel

The relevance of the quote was to counter your blanket statement that I have misunderstood Crick. Have I?

Thanks for the references!
I was very interested, as I surmised that this must be fundamental information, less than 5 years old. I am only familiar with Ediacaran fossils of primitive clumps and pancakes, lacking any of the distinguishing features of the species of the Cambrian explosion. Best, Mihkel

That was very good - thanks!
May I in return give you a quote from Richard Dawkins (The Blind Watchmaker), which I believe is very much at the heart of the matter: "As long as we can speculate freely about naturalistic explanations to nature and life we shall keep ignoring all the evidence that points to intelligent design, no matter how strong this evidence is, and even if it takes engaging in scientificacrobatics." This sums up a large portion of the discussion. Mihkel
