When Hawking talks about physics or cosmology, I pretty much assume he’s right. He’s probably well read on biology but I doubt he knows more then most amateurs. No evolutionary biologist has ever claimed dna came out of some primordial ooze, there are much simpler compounds that are capable of copying themselves. Add to that the shear scale of time, a billion years, that it had to occur then yes, life could have come from nothing.
Now short of building a time machine I grant we will never know that for sure but again, I have to use the best evidence
He seems to have lost a lot of bets with other physicists and his best days are well behind him.

One amazing thing about that is there is only one tree of life. In other words, abiogenesis only occurred once. There are other such "singularities" observed in biology that make me wonder at the odds of us being here.
Please believe me when I say that that I am not trying to be condescending; but given the HUGE number of variables that need to fall into place - in just the right sequence, for life to appear spontaneously, the chances are over-overwhelming small.
It's as unlikely as declaring that the below rock formations were found at the bottom of a rock-slide - and not just once, but over and over...
