I think with the questions I've put forth and with the answers supplied I can assert that The Theory of Evolution at some point cannot be taken back to its beginnings.
This is a "straw man argument". The Theory of Evolution does not attempt to explain the origins of life. It is a theory that explains the diversity of life after it started. The fact that it fails to explain abiogenesis does not prove that there is no naturalistic explanation for the origin of life. Abiogenesis is another field of study that has accumulated on its own an amazing body of work.
Before anyone denies it exists, you should know that there is plenty of accessible material from those that are popularizing the findings of the scientific community. By the way, here is an
example of science at work on abiogenesis. In the video you can see that although this is all speculation, biochemists have accumulated a large body of possibilities in the area of self-replicating organic molecules and how they can structure themselves into cell-like stable entities and then reproduce themselves. After watching this video, would you advise the scientific community to continue with this or to just give up?
In a similar fashion to which The Big Bang Theory (even mathematically) can't make it back past a few seconds after the Big Bang.
This is an "appeal to ignorance", which is a faulty rhetorical device that says, "if we are currently ignorant about some aspects of X, then we will never understand X". This is the exact opposite of how science works, which is, "if we are currently ignorant about some aspects of X, then its time to get to work in understanding X."
And yet atheists and disbelievers assert that creation can somehow be sufficiently explained in scientific terms to, in a matter of speaking, justify it all (i.e. creation). There is a measure of hubris and intellectual dishonesty in that. These people (Dawkins et al) have asserted some kind of intellectual superior position in the the discussion of creation (divine or by chance) that is simply untrue even scientifically.
This is a common complaint amongst Creationists that on this subject there is some kind of conspiracy where scientists all around the world are studying evolutionary and abiogenesis biology simply to disprove the existence of God because they are atheists with an agenda.
This comes from a layman's confusion between what is called methodological naturalism and philosophical naturalism. Philosophical naturalism is a kind of religious belief that says that there is nothing outside of the universe of purely natural processes. You might call it "scientism".
Methodological naturalism is not a belief, rather it is simply part of a discipline. As part of the scientific method, merely as part of the discipline, when confronted with a body of unexplained evidence, a scientist assumes that it can be completely explained by natural processes and gets to work trying to discover it. This is what a scientist has to do, because otherwise he is not doing what he is paid for.
This is also true for other disciplines, though. For example, in a court of law, any arguments involving divine intervention are not admissable. Why is that? Is it because everyone in the criminal justice system are militant atheists? No, it is because the moment you invoke supernatural intervention, there is no way to prove or disprove anything. So the law simply follows a discipline of methodological naturalism because it is incapable of doing anything else.
If there actually is divine intervention, the legal process is blind to it. It falls outside their jurisiction. How could a court of law deal with a defense that says, "I submit to the court that although my client was alone in a room with the murder victim, standing above him with a bloody knife in his hands, that a supernatural demon appeared, committed the murder, caused the knife to appear in my client's hands, and then disappeared, leaving no evidence that it existed."
You see, even if this was true, a court of law would be incapable of dealing with it within the discipline of how law is praciced. Since there is no way to test the demon murderer hypothesis, there is no way to surmise if it is true or false. It is, by definition, an untestable unverifiable assertion. So the legal system uses methodological naturalim because it can't work with anything else, not because all those involved with law are militant atheists.
In science, when we encounter an unexplained phenomenon, there is no special signal or signpost that says, "Sorry guys, there is no natural explanation for this.!" Lacking that, a scientists simply gets to work on it. This goes for biology and biochemistry as much as any other observed natural phenomenon. There is no bat signal that says, "Sorry, but cells come about through supernatural means, so give it up, guys." There might be a group of religious people who feel that way, but there is nothing tangible that allows a scientist to discern that a natural explanation for somehting is impossible.
In the case of Richard Dawkins and some others I can think of, I agree with you to a point. First of all, Dawkins is a prominent evolutionary biologist and his work in that ared should be appreciated. However, when Dawkins expounds on the subject of organized religion, he is not representing the scientific community. He is working outside his field of professional expertise, so he is simply an articulate guy writing a book about his opinion on organized religion. You might say that on the subject of religion, Dawkins is not speaking "ex cathedra".
