But the folk that trot out the magic button of panspermia are not much different than those who trot out the magic button of Goddidit.

I can't agree with this, Jar. For sure, the panspermia hypothesis is based on very limited evidence (mostly, as far as I'm aware, on the presence of animo acids in the aftermath of supernovae), but the concept of life spreading around the comsmos by means of the stellar lifecycle hardly strikes me as "Goddidit".
​
It's certainly a potentially testable hypothesis.

What I object to are folk pointing to Panspermia as an answer. It's not. In fact, it is simply a bigger pile of questions than anything we currently have.
​
Fair enough. Don't get me wrong, by the way - the Panspermia concept strikes me as frivolous when one takes into account the vast amount of chemistry that will have already existed on the planet from its earliest days.

I would bet that eventually we will find out that the transition from non-life to life is a pretty common chemical occurrence and we will have to revise our whole definition of "Living Thing".
​
I'd have to agree with you on this.
