papertyger: “None. Zero. Zip.
The Scientific/Cultural mandarins gave up on the question as unknowable and irrelevant.”
I think not.
In fact, growth in understandings of biology & chemistry in the past 63 years has been as great as in any other scientific field, for examples:
You haven’t been following very closely then.
Here’s the offical line on the subject:
https://simple.wikipedia.org/wiki/Origin_of_life#Spontaneous_generation
Notice that there’s nothing newer than the 70s quoted there? The reason is all the promising experiments for the basic theories of spontaneous generation came up false and now largely don’t like to talk about it.
The facts are that spontaneous generation seems less likely today than it did in 1952 but biologists refuse to discard the theory because it’s become scientific dogma. And when you require dogma instead of experimentation then you’re no longer doing science.
If you are arguing with BroJoeK, a criticism of dogma is going to fall on deaf ears. BroJoeK is dogma central. Dogma is his favorite method of arguing.

But we need DogMa, so DogPa will have someone to cuddle up to!

If you'd read the section on "spontaneous generation" you'd see that it was disproved by Pasteur in the 1800s.
Nobody since has tried to resurrect the old spontaneous generation hypothesis.
I recommend you take an hour or two to read that entire article on origins of life, plus some of its links.
Then go on to the article I recommended in post #100 above on abiogenisis.
I promise you'll learn something about real science you didn't previously know.
Then you'll be ready to put alleged "spontaneous generation" in its historical context and differentiate it from today's ideas on abiogenisis.
