Those are two things; evolution and abiogenesis. We have evolution well sorted, to the point where our entire understanding and implementation of biological science depends on it.
Abiogenesis is not as well fleshed out, but we are miles ahead on it now than we were even 20 years ago. Do we have a strict, proven explanation and timeline? No, not yet. Do we have nothing? Not even close. Is it worth throwing our hands up and going “I don’t know, therefore god”? I don’t think so.
I think you’ll find that most believers of intelligent design and a God being don’t think about it too hard. Obviously there are plenty of apologists in the world whos job it is to discuss and debate this stuff, but they are the faaaaar minority and most have a financial stake in the matter.
For evolution take a look at Gutsick Gibbon on youtube and for abiogensis look up Forrest Valkai. They’re both incredible educators.
