Re: How did life begin?
I only want to make a couple comments..since I don't know much about this specifically..and I don't think that a whole lot is known about it anyway.
There is no "atheist viewpoint"...there may be a viewpoint that is what most atheists believe..probably because it logically follows when you don't shove a god in there, but atheism does not demand that you hold any "alternative" beliefs..alternative to religious beliefs that is.
I believe that the only thing that is necessary as a "first life form" is a replicator..from there, it seems that the evolution that we know is inevitable...
I don't know about the specific estimations of likelihood that something like this would be formed...but there are a couple things that I think should be considered...1) the nature of the situation we are talking about...for instance, conditions that this occurrence is dependent on may have been more ideal at other times..and 2) whether there are even "smaller" steps that replicators..prehaps there are other, more easily formed, things that would help to bring about a replicator..but again, I don't know enough about the subject to be confident that what I am saying is true...just some random thoughts
