Considering that humans are the most intelligent species on earth, why do humans make infants?
I cannot understand the reason why humans make infants, when
humans can’t predict whether the child will be born healthy [mentally or physically],
humans can’t predict whether they will pass on genetic diseases that could occur at any point in the child’s life,
infants could be raised in poor environments, and
death is inevitable for every living being at some point of his or her life cycle.
Knowing all the above, why do humans make infants? Aren’t humans making infants for their own selfish interests?
