Can you show it's anything more than that? It'll probably take as long as it takes you to show it, JP, before I "realise" it.

Also, no one's saying DNA was the original self replicating molecule.

Quetzal,

Out of interest, how many "snowball earth" events were/are alleged?

I'm aware of the one just before the Cambrian explosion, & am dimly aware it wasn't the first. My reading suggests it may have been life itself that prevented the next "post" cambrian snowball, due to a change in gas concentrations, particularly oxygen.
