I've read many posts in these forums defending and debunking creation but I don't think that anyone has mentioned this simple reason why not only creation is false but evolution is the only rational truth. It is a simple biological fact. A healthy population of a unique species can not grow from 2 individuals. It would require constant inbreeding and the gene pool would not be diverse as it is in all species. If evolution is a fact, and it is, this would never happen because unique species would arise slowly from large populations with a large gene pool. Mankind could not have risen from one man and woman. Creationism is false and evolution is truth.
