1- Just admit we can't and our science can't reach that level,and very probably will can't too.As for cars and such, it's not organic, so it's not going to replicate much less procreate more cars.
To make flys in a lab, you collect eggs and hatch maggots until they pupate into flys.
2-this remind me about which came first egg or chicken
Mmm, So you will imitate the original method !!
Why don't you start with collect organs and combine them then starter it,as we do with cars ...etc?
