That time I described my life history to an alien being

 Today  I am on Little Rock, America and am pondering how to describe my existence should an alien being approach me and ask about my life. 

I was created 69.5 years ago. I do not recall this nor how it was that I came to be. The ones who created me cared for me until I was of the approximate size and intellect that you see today. This took about 20 years. 

After this period my human creators (not my divine or ultimate creators, that is another story) bid me farewell. I traveled a far distance from where I lived to come to this same city. I walked into an old building and met a female human (we have two kinds. I am male). We met many times. As I write this I am standing on a sidewalk outside that same building. 

I told her I had amassed powers of persuasion and could bend other humans to my will, particularly in commercial transactions. She told me she had the power to create small humans. My assistance would be required, which she would allow in exchange for an extended period of support in the form of shelter, food, money and other materials that she might require. 

I was skeptical but agreed, having difficulty shaking a spell she had cast upon me. She employed her creation power three times over the following twelve years. As these small humans grew larger she required greater support in the form of material goods. I provided this by exchanging knowledge I had acquired into money. This I then converted to cars, clothing, baseballs, bandaids, and larger shelters. This project took over 30 years until we finally bid the youngest human farewell. (Over time these created even more humans, five so far.)

We have now rested from this work and spend our days in play with the newer humans and traveling to distant lands sharing our story. No one believes us.
