Biologists seek much the same I think? But in the case of Biology the processes involved are natural ones.
In the case of biology and the processes of human development from conception the speed of countless cellular division into fully formed human.
Something that is that complex, doing that much work, executing with a high degree of precision, you think that at random, an unguided alteration could occur anywhere at any place, through evolution would be able to make new functions and forms and not screw up the entire process?
A lot of things are going on in our birth, to screw up something early in the coding could add or subtract from what is necessary down stream, screw up late all the major things are done.
What natural process do you think would make it a reasonable to adjust life on the fly without greatly damaging it?
I'm under no obligation to - research into the naturalistic beginnings of life carries on and I await developments with interest. There's nothing about life that forces the conclusion that it could not have come into existence by purely natural means.
If there was, Biologists would have reached that conclusion already.
Accept your definition of natural is not what we see taking place in nature. You cannot point out how what you think occurred “naturally” by anything we see today in our studies of nature.
You are relying on evolution of the gaps, so you are suggesting something supernatural took place and is still taking place.
These are worldview issues and all we have to go on is how realistic is the narrative we agree with. You can punt, claim ignorance, suggest others agree with you or you them, you just can’t justify your claims beyond evolution of the gaps.
