Do you think science is the only way we can ascertain the existence of God?

It must be clear that it is not possible to prove God by the usual scientific method. Then again one can't prove Abraham Lincoln either. The reason lies in the nature of history and in the limits of the scientific method. For proof it would have to be repeatable. But the beginning of the universe or the ination of Lincoln can't be proven because they can't be repeated. But the fact these things can't be repeated doesn't disprove their reality as events. To actually expect that the supernatural should be a subset of the natural, which grossly violates logic even at the grade school level.
