The congolmerate managerie of mass and light that you are existing in now is Universe #23.
Many trillion years ago, a pinprick of matter, surrounded by an infinity of white light began to expand. Eventually, Universe #1 slowed, and collapsed upon itself, but not without first creating some incredibly interesting forms of virii and algae.
Each expansion and contraction of this pinprick of matter is like a heartbeat, each time creating unique and beautiful forms of life -- some so wonderous they make you want to shout Stop and grab a flower and just revel in its beauty.
It is now Universe 23. Life is complex. It is the universe of the humanoid.
