I have no problem believing that such “conditions” have never existed on other planets, nor on Earth itself, if what you are implying is spontaneous generation of life from non-life, without intelligent action.
I’m not implying anything other than life on this planet has evolved over time, even knowing that does not completely explain history, for example no none has been able to fully explain how the Pyramids were built...
I do believe science this planet has been around for millions of years, there must be others out there similar to Earth were intelligent life exists...as I said some could be very similar to Earth some could be far superior, some could far behind Earth in the evolutionary process.
But it’s an opinion, one that may not ever be proven one way or the other.....
