Yeah yeah, I know, parents, genetics, etc. I got that. That's not really what I'm asking here. Why do I have the parents and the genetics I have? Don't go telling me about how "God ordained it" and "it's His purpose." Yeah. Heard that one before, and it didn't answer any of my questions.
See, I've gotten to thinking. Maybe there isn't a reason, and we're only different because, hey, that's just the way the world works. Normally an answer like that wouldn't convince a guy like me. (No really, answers like that have radically changed parts of my life. I hate those kind of answers.) But this time... this time it makes sense.
Let me explain; say (just for this example) that everyone is the same. We all look the same, have the same living conditions, etc. We would still be different. (Well, that or the world would collapse. But we'll get to that.) See, inside of everybody, we are all still fundamentally different. We inherently change our beliefs and behaviors because of one major factor that determines who every last one of us is: experience.
