We are the first beings to know and to create. That's a whole different level of intelligence. But to your point, the varying levels of intelligence show that intelligence - like life - strives to reach its potential.Are humans the first and only intelligent species on earth? If so it took 4.5 billion years and innumerable accidents to get to us, and one asteroid strike could have wiped out every intelligent creature on the planet.Not sure how anyone can watch that video and not know that life and intelligence was preordained by the laws of nature.
It actually took longer than that for beings that know and create to arise. As far as we know it took ~14 billion years for energy and matter to reach its potential. Granted, for all we know it could have happened sooner in some distant galaxy. I am not sure what you think intelligence being wiped out has to do with the purpose of the universe though. They don't really seem related to me.
