So, a bunch of gods were born in the expansion of the universe and some of them started messing around with it while others just relaxed. But then this one god, called the Asura, showed up and started killing everything in sight. Everyone was terrified of him because he was so powerful that he almost destroyed the entire universe. Even the immortal gods were scared of him because he started consuming their powers. Things got really chaotic because of him. Finally, the God of Time stepped in to try and stop him. They fought for a long time but the Asura couldn't be calmed. The God of Time used a spell to banish the Asura to the darkest part of the cosmos and trapped him in a time loop for millions of eons. The God of Time used his remaining power to rearrange the flow of time and speed up the process for the birth of a new entity, and that's when I was born. It's believed that all true gods are born from (Angkor) a cosmic womb in every 500 million eons.
