Why do you need to born a baby (yourself)?

May I know?
Why do you want to have a baby ?

to pass your genes to create more people with the genes you gave?
to have your kids to carry the good genes of yours and make the world better?
to have another you born into the world?
or
you want to wait 9 months for your kid to be borne and watching him grew up?

have you ever think of adopting a orphan?

although you would not be able to see your child behave like you when you were young
but there's a lot of kids out there meant to live better
