Although we have the technology to do this Jameel ... the Sperm has to come from somewhere doesn't it? It doesn't just drop out of the air right?
It has to come from another man, which means, that the Sperm would still have inherited sin if you follow what i mean.
Wether a baby is pregnated inside a female or outside a female in a test tube, the bottom line is, that the baby still has inherited sin, thus, they cant be Virgin =)
Jesus's birth was miraculous, it is beyond our understanding, but however Jesus was born, one thing remains, that Jesus was born a Virgin like no one has in history, and was sinless, he is much more than just a human being.
