i think its funny how people discuss the world and life. they try to find the meaning of it whithout understanding that every thing in this earth is only relevant to earth.
To truely understand life, you must consider everything that has life and how it evolves. After all, everything that "lives" goes through a process of change.
Do most people that question life take the change of all the universes into consideration? from the sub-atomic universe, to the cosmic universe; we question life as if we were the main acts of life. You say you are here for a purpose? what purpose could that really be? if you take into consideration the universe, you will find that you are truely insignificant.
however special you believe to be is just an extention of your ego. you only play a small part in life which is nothing when taken that human life will never have ny significance in the lifespan of the universe.
sorry to say, but the theists have it the worst. they believe that the universe was created by "god". If they truelly understood anything, they would know how our universe was created. instead, they choose to argue with very weak points that have no value. believing that everything was created by a higher being, they sell themselves short and will never leave themselves room to grow. let me ask, what influence does god have on a neula multy billions of light years away? what influence does god have on the electronic particles in atoms? was god a phisics major? did he plan out how the cosmos would destroy and create themselves?
in short, we ponder about life, yet there is so much we never consider.
btw, god said "let there be light". he didnt say "let there be a nuclear ball of gases that change hydrogen into helium which creates energy which allows life in this solar system (not just earth).
