so i was thinking. its my theory that we are born into this life solely for the purpose of evolving our souls. and once we fully understand all that it means to be human, and have attained complete wisdom and enlightenment, we are then no longer evolving on the physical realm but at a higher level until finally, we evolve back to the beginning. in the big bang theory with its unfolding universe, what this means is that at some point of the expansion, our realm came to be and then as the universe reaches the point where all that unfolded starts to evolve to higher frequencies, the universe starts collapsing back in until we reach that void which existed just before the big bang. in a way, it is like breath. the universe breathes out, the universe breathes in.
