You have to divide this into two questions: How would I formally falsify abiogensis? By examining the entire state space of the universe as if it were a giant chess game I could read backwards in time and constructing of eden proof: ie, a proof that some point in evolution could not be reached from a starting point with no life in it.
As Hoyle and Morowitz did.
I think it is a safe guess that humans will never have enough resources to attempt this proof.
So it can't be falsified. (This means it has fallen as a science,)
Kindly submit your proof that the approaches I have suggested are the only possible ways to falsify abiogensis.
They, of course, did nothing of the sort. In terms of my suggested computation, they picked one back-vector out of countless trillions of the back-in-time computations that would be required to examine the universe exhaustively. As they say, it's not that you're right; it's not that you're wrong. It's that you aren't even in the game.
