No, your neighbor isn't your baby, you weren't around her 24/7, you weren't ever really responisble for her all the time, your not old enough to even get a job, how will you support it?
You think that your parents will pay for it all, how would you feel if you knew that you had to rely on your parents for everything your baby needed? It wouldn't even really be yours if you did that, it would be your biologically but you never were able to provide for it, your parents did.
Do you think that if you have it with a 13-14 year old BOY, not man, BOY will want to take care of it, they may say they do but you never know. So think of it, your in what 7th or 8th grade, not even in high school, would you go to school? I mean you can because I do because there are programs in some areas of the USA but does where you live have it?
You really need to think of all these things, if you have a baby it's not what you want anymore, it's that baby, your secondary, so when you get older and want to hang out with your friends how will you be able to with a baby to take care of, just hand it off to your parents.
Just think, don't you want a child hood?
