No - I wrote that.
I have supported my reasoning with the simple fact - which is recognised by any unbiased person who has no vested interest in denying it - that there are overwhelming odds against the occurrence of one specific set of circumstances in all possible universes.
Again, that is not support. It is just repeating your assertion along with the assertion that it “is recognised by any unbiased person who has no vested interest in denying it” - whereas I
have explained why I think it is not just an unsupport
ed assertion, but one that is unsupport
able at our current level of knowledge.

I have supported my reasoning that fortuitous abiogenesis is highly improbable but you have rejected it without giving any reasons for an alternative explanation.
supported that assertion, you have simply repeated it over and over. I have explained (e.g. in
this comment) why I think this is an almost impossible assertion to support, but you have not even tried to do so.
False! I pointed out:
(i) Scientists are not indulging in a guessing game when they refer to the likelihood of life on specific planets.
A rather confused statement, and one which in no way seems to support your assertion that “fortuitous abiogenesis is highly improbable” - if anything it seems to contradict it, or at least imply that scientists disagree with it.
It might help if you cited the statements by “Scientists” that you are referring to.
As far as giving “any reasons for an alternative explanation” - I don’t
need to do so in order to point out flaws in your reasoning.
(iii) The total number of possible universes far exceeds one universe with the conditions necessary to support life as we know it.
An unsupported assertion followed by another unjustified restriction of life to “life as we know it.”

For example, why should a universe in which the laws of chemistry make it likely
for complex self-replicators to arise not also have large numbers of asteroids smashing into it’s life-friendly niches?
You automatically equated living organisms with complex self-replicators(…)
No I didn’t. I used the development of complex self replicators as an example of an important possible step in the development of life, just as I used asteroid impacts as an example of a possible cause of the extinction of life.
The origin and survival of life over billions of years are based on the same fundamental conditions.
As I just showed, no! The
origin of life and the
survival of life depend on totally different conditions.
How many other universes are possible?
I don’t know. Any answer from ‘zero’ (if ‘possible’ universes exclude those only made ‘possible’ by supernatural intervention) to ‘infinity’ (and bearing in mind the various infinities defined by mathematicians) is defensible, more or less.
You are the one making positive assertions about other universes.
You enumerate them, if it matters.
False deduction! The fact that scientists have specified a few planets where they consider life to be likely to exist doesn’t imply that abiogenesis is fortuitous.
Are you claiming that those scientists assert supernatural reasons for life being “likely” on those planets? Again, I think it is time you cited these scientists.

In other words I have not made the bold unsupported assertion you want, nor am I going to run around shouting “There is no God, Jesus never had a beard, Mary Magdalene was an apostle!” just to give you an easy target to attack!
Your sarcastic comments are out of place on a philosophy forum, infringe the conduct rules and reveal more about your personality and antipathy to Christianity than anything else.
There is nothing sarcastic or antipathetic to christianity in saying that I will
not make such assertions. If you cannot defend your assertions, that does not require me to make baseless assertions just to give you an easy target to attack - nor would you doing so in any way justify your original assertions.
Nor do veiled threats against me in any way strengthen your case.
You have again evaded the question. Do you deny that the number of unrestricted possibilities is far larger than the number of possibilities restricted by specific conditions?
Again, that depends on the conditions. I gave one example of a condition that
in no way restricts the original set of possibilities.
You make the assertion that only a tiny fraction of the ‘possible universes’ could give rise to life, so
you need to support that assertion.
Any form of life, not just ‘life as we know it’, if you want it to mean anything. Otherwise it is just a
post de facto observation, like rolling a die a million times and
then claiming that the infinitesimal chance of
that particular series of numbers being rolled is proof of God.
If you had predicted the series in advance, sure, or if there were something unque about the series, maybe, otherwise not so much.
