As a parent, for me this question is as valid as "what's the point of falling in love". I could try to come up with some valid scientific answer, but the truth is that you won't really know until you see your first born. It's like explaining the beauty of the mountains, just by looking at the picture. You can't really do that. You have to experience it yourself.
I guess I couldn't explain it better then Robin Williams in "Good Will Hunting". https://www.youtube.com/watch?v=qM-gZintWDc
