I'm currently designing an advanced peaceful alien civilization.
In this civilization almost every individual has approximately a few hundred clones of themselves across their planet or even the universe.
Here's how the thing goes:
First and foremost it is important to say that their species' bodies are techno-organic and that they are immune to practically everything that could kill a normal being. Meaning that they don't need any sort of medical care, and that the clones are not meant to be used as a way to ensure the survival of the individual by let's say, organ transplant.
Second of all, the clones are not created in the midst of the individual's life. You see, their species' infants are grown inside special capsules. You first describe how you want the infant to be like (think of it like designed babies), then you wait a few hours and then he or she is ready. Though they don't create just one infant, they create all of its clones with him/her. Basically it's like a large cocoon from which a bunch of similar looking infants come out. The family then takes the babies, grow them etc.
However, I've been thinking, why would a society want to have clones of themselves, what's the reason?
I mean, since they're peaceful they obviously aren't meant for an army, if they're basically immortal then they don't need them for medical support, plus they're not used as slaves if that's what you're thinking like in most movies, so why would they want they want to have clones, or more accurately, why would they want their children to have clones of themselves.
