If the third human on this planet DIDn’T come from two other ones..
WELL THEN.. you are forced to concoct/make up/compose a BIG Yarn.. a Story.. a Tale.. to explain it..
Dawkins is quite good at it.. call it Science Fiction.. or Creative Factoids.. or Academic Fund Raisers..
Fiction must believe believable else whats the point...
Reality need not BE logical at all to humans..
What is.... IS... and What ain’t..... AIN’T..
Where did the third human come from?..
Indeed. Thank you for sharing your insights, dear hosepipe!
The species we are did not come about in one or two generations.
