Let's see the studies backing these claims up.
We're getting lax here - we're saying anything is possible with
no facts to back it up.
Either say this is speculation or this study suggests -
I think its time to start dumping some of these origin of life
aspects that really don't have anything but speculation behind them:
silicon in place of carbon, panspermia, frozen earth origin,
Cairns-Smith clay crystals, life on gas giant moons, etc.
