I agree. We're long overdue to wipe our hands of abiogenesis, and come up with another hypothesis to test.
Abiogenesis is simply the proposal that life emerged from inanimate matter. Unless I'm mistaken, there is a detailed explanation for that in the bible. If that's one of the other hypothesis that you'd like to test then I'll be keen to know how you propose to do that.
I'm going to assume God exists for the rest of this post. However, I see no evidence for biblical creation. But I see a gargantuan amount of evidence for evolution. You could say of biblical proportions. So I would suggest that God didn't shazam everything into being over a short period of time. But that He set up his creation to unfold in the manner which we have determined over the time periods which we have also determined. I'm going to call this process 'natural' (yet accept that it is God's handiwork).
Now, in the same way that we can't test evolution through from, say, bacteria to man, we can't test a natural process of abiogenesis. Because the proposal is that under conditions of which we aren't exactly sure of, over periods of millions of years, untold numbers of mini experiments were being carried out in some verion of the primordial soup every single second accross an entire planet. Which eventually produced, not life, but inanimate material that had one or two chacteristics of life.
And that, according to the process of evolution that we understand so well, the gazillions of experiments built on those first small steps and added further characteristics. Until we had what most people would agree to as being life.
Now quite a few of those small steps are readily understood. And we can exoeriment to show that they indeed could have taken place. So we have this monsteous jigsaw puzzle to which we are very slowly adding small pieces bit by bit. Stick around long enough and we'll have a larger picture.
In the meantime, you can suggest how any other proposal might be tested.
And, bear in mind, if we ever find evidence for life elsewhere in the cosmos, then we won't need to do any more tests. You've quite a lot of eggs in your one basket...
