Relocating to Germany ..... returning "home"

I found a few years ago (upon my father's passing) that I was born in Germany while he was stationed there with the U.S. Army. I was born in 1972 and have lived in the States for the last 41 years.  Do I have any citizenship rights since it has been so long?

German citizenship is inherited, not given by being born in the country.
Was your father German citizen at the time of your birth?

No he was stationed there in the U.S Army. Both my parents are Americian Indian/German/Irish and Dutch. Both U.S citizens

Then you have no claim to be German, at all. Only your parents' citizenship at the time of your birth counts.
Like any other (non-EU) foreigner, you can only become German by living here for 7 or 8 years without needing state financial aid, and show good integration (mainly language). You also need to renounce any other citizenship before you get the German one.
