“In so far as a scientific statement speaks about reality, it must be falsifiable; and in so far as it is not falsifiable, it does not speak about reality,” wrote Karl Popper in The Logic of Scientific Discovery.
I don't agree with Popper about that, but I'll avoid the technicalities.
I agree that assertions about origin of life (OOL) are usually not scientific conclusions. Mostly, they are speculative hypotheses. However, that's not a criticism. A lot of science starts with speculative hypotheses.
OOL is particularly difficult, and possibly we might never have a clear conclusion.
Finding other planets with life would be interesting and might give insight. But the distances to such planets might make this difficult.
