You can't.The only way to meet aliens to have a male sim get abducted and when he comes back,your sim will be pregnant.You won't notice it,but like female sims,in a few days you'll have a baby alien.
Male elders can get younger Sims pregnant, female elders can not get pregnant.
the pity is you can't have a baby on the sims 2 ps2 and, there are no cheats :( how come you can hav a baby alien then?
yes you can, although i am not 100% sure how yet, i know that if a man gets abducted by an alien they get pregnant. If you want the aliens they are in the sims 3 season expansion pack.
