I appreciate your zealous pursuit of truth, friend; I really do.
But, as I remember, all species came from, at one point, a singular organism, according to the atheistic worldview. Would that not be the severest of bottlenecks? Yet, amazingly, life "recovered" and we have not only great DNA variation, but an enormous number of entire species of living things. I cannot imagine that a flood such as the one described in Scripture, which happened we are not sure how long ago (it could have been aeons), would have created the bottleneck you describe, much less one which would be observable even today. I still am not convinced at this point by the evidence.
First life would have been bacteria like. Reproduction there is quite different from today in complex multi-cellular things.
Populations sizes of less then 200 being problematic for the survival of the species is true in "modern" species... Like rabbits, crockodiles, dinosaurs, humans, etc.
In the very beginning, we talk about "self-replicating molecules" as the "first life" thingies. Those were quite different from what we have today.
There was no sexual reproduction back then either, which also plays a big role in survivability of a species and the importance and implications of genetic variation.
Asexual reproduction is very very different. Every "new generation" is essentially a clone of the "parent", with a bit of variation.
And off course.... that "first life" was at least 3.8 billion years ago.
But, to be frank, the primary issue here is far, far upstream from where we currently are. This is a worldview clash, and those are not resolved easily, if ever.
Actually.... the only worldview that's being "clashed" here, is YOURS.
I'm not the one here with the relgious/dogmatic attachment to any particular view of history. I just go by the evidence... YOU are the one here who thinks to have the answers before asking the questions.
It's YOUR "
worldview" that's being challenged by the actual facts of reality.
YOUR "
worldview" is shaped
beforehand by your religious beliefs.
While MY "
worldview" is dictated and shaped by the actual data. And before having such data, I just simply acknowledge that ignorance and say that I don't know.
We both have faith in different authorities
Nope. YOU have faith in an authority, yes... which turns out to be a bronze age religious book.
*I* have no such "faith" and I most certainly don't have any "authorities".
I just go by what the data suggests. And I also do not "believe" anything. I consider things likely and unlikely. And the degree to which I do, will be dependend on a combination of actual evidential support, testability and scientific consensus.
, and we both assert that the said object of our faith is infallibly true.
Nope, I don't do that either.
NOTHING that I consider "likely" or "unlikely" is done so with a degree of "infallibility". All is up for questioning. All is up for doubt. The question is how reasonable the doubt is and what evidence we have at our disposal to support the stance we take.
It's always the evidence that determines how "certain" I am about something. And I never consider something certain for "100%". Some things are SO LIKELY that we might just as well call them facts, sure... But then still, I'ld never put it at 100%. It'll always get stuck at 99.999999999....%
Fortunately, contrary to what many think, the Christian worldview, alongside believing that all truth is God's truth (which includes science), also believes that we simply do not and cannot know everything with certainty (and this also includes science), and that we as a human race will be constantly learning new things until the end. I think for everyone an acknowledgement of fallibility is crucial.
Yes. As I have said above.
However, that doesn't mean that we get to reasonbly doubt anything.
For example, that the earth orbits the sun and not the other way round, cannot be rationally doubted today by any sane and educated person.
Does that mean that we are absolutely, infallibly, certain that the earth orbits the sun? No. It just means that the evidence we have at this point makes it completely unreasonable to think otherwise. But for all practical intents and purposes, we call that a fact and true (small "t").
With that in mind, I would suggest a little more tolerance on your part. Ridicule, sarcasm and superiority complexes never help these conversations, and only drive your conversation partners away.
Sorry, but I feel that sarcasm, ridicule and a sense of intellectual superiority to anyone who thinks the biblical flood story is literally true, is MORE then justified in the 21st century. Especially if that someone lives in a first world country and has access to the internet.
To believe the biblical flood story to be literally true and that it happened somewhere in the past few thousand years, is quite on par with denying embryology and believing in Stork Theory.
It's insane.
Anyways, I will look more into the issues
Please do and don't be afraid to ask questions. Plenty of people here, including me, will be more then willing to help you out.
