Evidence for God from Science

Has anyone seen the movie K-PAX with Kevin Spacey? Was the guy really an alien in a human body from the planet K-PAX at the end, and he really did go back through the light? I need help on what REALLY happened. I am confused, as well as my parents . Kevin also mentions in the special features that he thinks it is arrogant to think we are the only living intelligence in the universe. Agree or Disagree? Would more intelligent life support God more?

What Kevin Spacey calls arrogance is scientifically backed....(to an extent...not saying there is no other life, because that's proving a negative...)
