Zacharias: don't worry, everything's okay, heh.
The absolut origin of the runes is unsolved, but theories are many, here are ie. tree of those:
1) The runes were developed from the Hellenic and Roman alphabets in 500BB till 400AB (before and after the bastard, haha)
2) The goths developed the runes from the Etruscian alphabet in 200BB-100BB
3) The runes were developed in the Stone- and Bronze Ages from the ancient Hallristningor-engravings found in the regions of northern Italy, the southern Germany and Austria
But again, nothing can be said for sure, go figure, hehe.
Numerous sorts of runes has been in use, but the biggest and the best-known runic alphabets are germanic, anglosaxic and scandinavian runes, of which the germanic is probably the oldest, which can be seen when looking at the movements of germanic people taken as a whole.
One should still be careful and sceptical when searching after information about the "magical" meanings and functions of the runes, because every sorts of new-age crap lies behind every corner. All that can be said for sure nowadays is that the runes have been a means of writing and even every day work, but much of the real and veracious information has become destroyed and/or become crooked by a way or another when time has passed.
It's pretty funny how ie. the net is full of "information" about "rune magic" etc. but there is nothing about such at the Nordica, the library for Scandinavian languages that is probably one of the best, widest and most trustworthy databases in the whole Finland when it comes to everything that has something to do with Scandinavian countries, languages, culture, history, arts etc.
