The only thing I am sure of is that humans do not evolve,
this is true but only due to our modern medicene because you can see that we did evolve due to sicle cell anemia, which holds a direct relation to malaria but due to vaccines and iron lungs and stuff like that our only hope for survival is genetics, if there was any hope at all, considering that if you do beleive in evoloution, that would mean that about 98% of all species that ever lived are extinct
