Do I believe in 'God,' yes or no? No.
In my opinion, Christanity is simply the most recent in a long line of religions dating back to when neanderthals/early humans quelled their anxieties about existence and death through made-up 'supreme beings.' The Gods of ancient Rome and Egypt were no more invalid as today's incarnations at the time. Egyptians had no knowledge of 'Christ' or the Christian 'God' because that particular religion had not been invented yet. But their gods of the time suited them just fine. There was no Christian heaven or hell during that epoch but I can bet you Ra and his fellow Egyptian gods had the same promises of delight mixed with damnation.
I do also believe there must be life elsewhere in the universe. And in, perhaps, multiple universes. We're talking sheer numbers here. You can use the Drake Equation and arrive at approximately 10,000 unique and technological civilizations in our Milky Way galaxy alone. Multiply that by the number of galaxies in our obsevable universe (200 billion, give or take) and I think you can see that life is most likely abundant in the cosmos.
Evolution? Yes, proven. Fruit flies can mutate at an incredible rate. That's why they're so popular with researchers. Mutation is the backbone on which Darwin's work was based. A slight genetic mistake that would turn out to be either beneficial or, at worst, fatal to an organism. Those that accidently received a 'good' mutation perhaps gained bigger wings as to avoid predators more efficiently. This allowed the newly-mutated bird a greater chance of surviving and passing on this new advantageous gene. Those with a newly-acquired 'bad' gene mutation (again, by chance alone)would be more susceptible to disease or deformity and would not be as likely to procreate succesfully. Genes don't care if they give you the prettiest blue eyes or a huge tumor. They just do what they're programmed to do.
Here are my thoughts on my own death...
1) Suspend heartbeat and breathing.
2) Lose consciousness forever.
3) Decompose.
No pearly gates in my future. Whatever it is that is me will simply cease to exist.
