"And at one point inbreeding stopped and that is what caused the human population to become larger than it should be. Allowing genes of weak members of the species to thrive, is probably human species worst mistake."

I think this statement is wrong. When inbreeding stop. Only human population thrive. Any species that practise inbreeding are heading to extinction(proven). Example: Tasmania tiger, Black Rhino.

"Proof of that is found when livestock breeders perform selective breeding and culling. This process produces the "best" livestock based on the criteria that the breeder has chosen."

Selection Breeding is different from Inbreeding. Selection breeding is to chose the best stock to breed with another different stock. Which means, selection breeding is to avoid inbreeding.

Inbreeding only works on stock/ornamental pet. Which also proven to create more undesire offspring that usually deform. Which end up more culling.

Inbreeding also reduce the gene pool which will wipe out the whole species if disease strike.

For example: HIV kill Human. But due to the large gene pool in Human. Scientist already found a minority of human actually immune to HIV. Therefore, If whole world infected with HIV. Most probably african will survive.

"was not the whole population of the world started from inbreeding?

how did adam and eve was able to copulate and eventually populate the world with 6 billion people? "

Yes. Human start from inbreeding... but adam and eve(if you believe adam n eve) did not populate the world with 6 billion people thru inbreeding.
...............................................................................................
Consider this:
a pair of monkey produce 12 sibling (assuming 6male/6 female). This sibling with eventually mate among the sibling... and the cycle goes on. Because they have the same genetic pool. If a disease strike, 99% of these population will die out (or survive) depends on situation. That's the advantage/disadvantage of inbreeding in long run.

In short-run, if the sibling above inbreed and produce another 12 babies, its possible 10-30% of it die-out due to inbreed because recessive gene are usually carries disease.

"Why are you not mating with apes?"

Because they will chew ur cock...
