How did the universe come into being? And how did evolution unfold? Is Darwin's theory of evolution correct, or was everything different? Where do humans come from? Where are we going? And what will happen to us and the planet if we continue to exploit it? Are we on Earth to learn, and after death will we return to our true home, or will we turn to dust and everything will come to an end?
Questions upon questions. I don't have definitive answers to these questions either, but I will point out a few possibilities that are worth discussing.
Everyone should believe what they think is right-we will only find out the answer after we die, or maybe not!
