imo you cant have evolution without some form of abiogenesis which is why i include that aspect into my definition...although im aware that evolutionists dont consider abiogenesis as part of the theory.
What other science do you make this demand of?
Does Germ Theory also get rejected because IT doesn't include the origin of the life that IT depends on?
Do all of the earth sciences (geology, climatology, etc.) require the inclusion of a complete explanation of planetary formation to be included as THEY can't operate without a planet existing?
