Our evolution is to spread knowledge of the SELF from this earth to the whole cosmos.
Like us there are so many planets inhabited by life forms who are also just enjoying pleasures of material world.
3000 years earlier we used to travel in whole of our known and unknown universe through out of body experiences . Then due to changes of Yug we forgot everything.
Now with the use of space shuttles we will explore our galaxy . This evolution is because of our purpose to promote SELF knowledge through Realisation. In sat yug SELF knowledge will be shared physically with other worlds.
All this will take many centuries in the future.
