Does God exist? Explain what you take to be the strongest argument or reason to believe that God exists or the strongest argument or reason to believe...

When I look at
the scientific evidence of how our world and our planet came to be, I cannot understand a
disbelief in God.  It is too perfect and too precise to have happened by chance.  As to how many
Gods there are, I personally believe there is only one.  I agree that some cultures have
invented gods and/or goddesses to explain the world around them.  For instance, it is often
believed that the Greeks invented the story of Zeus to explain the lightning.  However, I do not
believe that all stories of any god are a myth.  As to the difference between humans and God, I
would say we are as different as the potter and the clay.  God is a supernatural being while we
are carbon based life forms.
