Panspermia can't be dismissed, we know even bacteria csn survive in space. But it would be unwise to slow down our work in abiogenesis in exchange for a panspermia hypothesis, at the moment certainly. We still have a lot to ask and rule out before we go in that direction.
The advancements in abiogenesis now we believe RNA is the original code, are significant and it is exciting times to be alive and able to learn.
Saying all this, I am open to thr idea of panspermia and for some reasom find it a comforting theory. Maybe because it eliminates our loneliness in the universe.
