Sure, it may be possible, just like everything may be possible. The difference with "abiogentic atheists," whoever they are, is that there are no extraordinary assumptions being made. There wasn't life, there was life, therefore life started somehow. No need to invoke a higher power when there is no evidence for one.<quoted text>
Butifmaybepossible. The basic vocabulary of abiogentic atheists. You add duh to it.
There is lots of anecdotal supernatural events going way back in time. Just because they didn't happen in a lab doesn't mean they didn't happen.
And do you really think anecdotal evidence means anything? There's anecdotal evidence for leprechauns too.
