I do not have the time to write a response to the entirety of that much like I had no time to reply to the entirety of the original post. So in short you are correct there is no explanation for how it all started as far as science is concerned. However just because science gives no answer and the bible does give an answer does not make the bibles answer correct. You see small scale evolution in England its very apparent. Go back 3 generations and many English men worked in mines. The average height of a white English male is good chunk taller now than it was before. Yes this isn't long scale yes this is just a reverse of them getting smaller to fit in the mines. Humans won't evolve much if it all now at least not in a permanent way. Much like the sharks haven't evolved much since the time of the dinosaurs. Because we have no predators so their I no natural selection. The smart humans generally produce 1-3 if any children and many less intelligent humans have upwards of 5. I believe if anything the human race will devolve. As to your question of would I love a disabled person the answer is probably no. You do realise its only positive genetic mutations that improve a species. Missing a chromosome ect. Will not improve the human species so your argument is irrelevant.
