Which is it? Does an infant/child need both a mother and a father?

you dont have to be married to have kids, alot of people arent married that have kids, alot of single parents raise children, my husband grew up without a dad and my dad raised me, i pretty much grew up with my mom in and out so i really didnt have her there mainly my dad. when adopting single people should be able to adopt because not every one wants to be married but they still have the right to have kids.
