where did the original concept of reincarnation come from?

[loopylucid]

Ok, so every now and again I like to delve into areas of which I have no belief in, just to check myself mostly, see if anything changes etc etc.
I do not believe in the stereotypical explanations for a few things, reincarnation and past lives are among them.

So I was pondering things and drifted into a state of non planned obe, where I began to express my pre ponderings, when suddenly I stopped relaying because I was asked a question, which consequently bought me bk, so im wondering if its going to lead somewhere and I always like a bit of research to get my teeth into!

I was simply asked, Where are the origins of reincarnation then?

And I thought for all I have read up on and the amount of people who have tried to persuade me otherwise with ideas! ive never bothered to find that out.

So I did a small amount of looking already and it appears, no-one is really sure? Or maybe I need pointing in the direction of information, I haven't come across yet.

So yeh just interested if anyone has any knowledge of the origins of this concept, where did this originate from? or by whom? Or is it infact the case no-one is really sure.

I get its history through the years in different belief communitys, but where did its energy expand from? If that fact is even out there lol
