He and others have at least speculated on both problems. They, at least, can point to a naturalistic of origins that make sense.
ToE has yet to do that with abiogenesis.
Bear with me. Solid science deals with areas where we have definite knowledge, good evidence. Speculation deals with areas where we have too little knowledge and information to make definite statements which are confirmable. Science is divided into areas of study. Quite often one area of study theoretically rests on another area of study but, and this is important, we do not need to have the originary area well worked out to be able to study the derived area.
