@DNA Thumbs drive,
Dwkins isn't even a proponent of any kind of abiogenesis. (You caught yourself again). Hes a proponent of panspermia.(Like Fred Hoyle), hes been a panspermiac since the early 2000's)> He even amits that to Ben Stein in your clip.
In his 2009 book "The Greatest Show on Earth" He mentions NOT ONE JOT about any kind of life genesis on this planet. However, this book is replete with eaxmples of recent evidence re: evolution >(After life had already been established on earth)
Interestingly, in these fora, Ive been consistently a vocal non-fan of DAwkins because he IS an asshole who gets his jollies by purposely bothering believers(Science is NOT about stepping on others shoes unless others step first). AND THEN he puts off the entire issue of genesis of life on earth by claiming that life first landed on earth from somewhere else. All that does is put off the entire issue of how and where life began.
The only way he could conceivably be considered is if we , as we wander away rom our Solar System, find the prebiotics associated with nucleotides and at least find RNA in the depths of space on other "goldilox" planets.
