The human race has not yet seen an Alien and still do not know if they exist, so nobody knows if they have genders and if they do we do not know how to tell one from the other.

You can get alien babies by creating two green Sims, a girl and a boy then make them...ya know. Then when the girl has the kid it is green like an alien. If you just want an alien kid both the parents are normal then i guess you are screwed. ha ha
check if its a boy or girl first
