My very personal believe is that God's existence is be beyond any scientific fact.

When you believe in God, its just the most primitive self-preservation instinct manifested as an unconscious rational choise.

As Blaise Pascal stated more than 350 years ago:

He chose to belive in God, because there is no proof that God doesn't exist.

...if God exists, the reward is heaven, and eternal joy.

...but if God doesn't exist, there is nothing to lose.

So, its like an insurance policy.

It's better to have one that possibly you are not going to need.

...than to need one and not to have it.
