How Ponies Reproduce

My theory on how the ponies of Equestria reproduce to create other cute, adorable ponies is by either one or two methods.

Method #1: They have sex.

Method #2: They build them like robots, the colts and fillies of the show are all robots. Scoots, Applebloom and Sweetie Belle are the leaders of the built revolution, maintaining their robotic components by not achieving their cutie marks(Which we all know that as it is earned, the mark releases the mixed chemicals stored inside of the children at a young age, causing the chemicals to melt down the remnants of the robotic skeleton, replacing and coating it with a bony substance.) So yeah, robots.
