There has been overwhelming discussion on existence and non-existence of God in this thread. We can not be rational and in the mean time prove the existence of God. That is why almost all religion demand blind faith from you.

But what is special about us human Being ( Homo Erectus),that is different form tiger, dog, plants, stones or snakes. We have consciousness, and can delve over our existence. Who we are? Where we came from ? Where we go after the death? But other animals can not do this. Among all the flora and fauna existing on this blue planet why only human being can do this? Are only we human being a special creation or favoured species of the GOD? But have we found the definite answers on our existence? It is big NO.

Does Cow or goat exist for us human being to provide milk and bread and mountains and nature exist for our happiness ansd contemplation?

That is why in my earlier thread I have quoted Darwin. Evolution is a fact and no body with rational scientific mind can deny this. About a million years ago ( the date may not be exact) our forefathers learned to walk on the earth with two legs instead of four legs, may be forced by some necessity.This forced our brain to develop further and gradually we developed capacity to think and plan.

There may be some super natural forces behind the whole drama of creation of the universe and evolution of species on the earth. For further exploration you can read Richard Dawkins and Stephen Hawkins (there arguments for natural forces behind the creation) and Paul Davies ( His arguments for some purposeful hand behind the evolution and creation of Universe. But recent scientific research are pointing, no purpose behind the creation of universe. It is just spontaneous, and governed by physical laws and we exist because this universe exist and the earth has right climate for evolution.

Scientists are talking about multiverses, consist of billions of universes and not with three or four dimension but with twelve dimensions. It seems bizarre and out of our level of consciousness. For quantum physics there may be another universe just behind your eyes, which we can not see. That is what the greatest living scientist Stephen Hawkins means when he talks about the universe with multiple histories. If you are amateur and no background of science, quantum scientists do  look like  a bunch of madmen.
