Became a Deity because of the mind
A common woman in Eastern society has nothing going for her, as well as 0 expectations in life. With a middle class wage she gets through her daily life without paying much attention to anything in particular. Only the big things bring up a flame inside of her like the misteries of the universe, the endless possibilities that science can provide, the vast and seemingly endless human knowledge and the intricacies of concuiesness.
Her free time is spent reading filosofical, political, history and psicological books. But her intelligence doesn't put her above anyone else or allows for beyond the world opostunities to be found like she would like.
One day, seeking to go further than reading what someone else wrote, she decides to go on her own mental journey to try and fill the interest void in her mind.
She spends entire one week doing nothing but fulfilling only her utmost important needs like food, water, sleep and bathroom necessities, and spends the rest of her time thinking and writting about anything that comes to her mind wothout any chain that would stop a train of thought to be explored like morale or ethics.
In this journey she never quits to return to the real world, and immerses herself even further every day on her trip only to find the source of life and counciousness inside her mind. Now that she has found this truth, she explores it and maintains contact with the being that exists there realizing that everythig is connected with each other.
With the culmination of her trip, she now obtains unfathomable power enabling her to do anything and everything.
Now there is only one thing left to do, try and convince humanity of opening its eyes and see how unreasonable they really are. It is well withing her reach to manipulate every human being into acting a more cooperating way from the beginning, but that would just make it world domination and not humanity's redemption. So, no matter how long it takes, she will convince every single human being that they are all stupid and that they can and need to start cooperating with each other.
