First I will say that on the scale of 0 (no doubt about God's existence) and 100 (complete doubt in God's existence) I am at about 98.5. I cannot go all the way to 100 because the atheist is just as dogmatic as the believer.
Some of the new things being discovered in physics and astrophysics that cannot be explained with the knowledge base we currently have seem to suggest that there are other dimensions beyond our ken. What makes it bizarre is that the effects of the events that happen in those dimensions can be observed in the dimensions we know and can observe.
For example, one of the things all of us have come to accept as "immutable fact" is that nothing in the universe travels faster than speed of light. Now, astrophysicists have discovered that there are action-reaction events that can span significant distances of the universe, even across the entire known universe. How does that happen?
And there are lots of other similar discoveries that, at the very least, give pause to the assumption that we can know one way or the other whether God exists.
Science marched forward at an astonishing rate since the 17th Century with one phenomenon (often attributed to God) after another being stripped of the mystery that shrouded it from the beginning of human existence. Now, we have entered a period when the answers are not coming so easily or quickly.
So, it is the complexity of the universe and the unknown dimensions of space and time that make the belief in God (who must have no limitations imposed by the dimensions we know), at least, reasonable. On the other hand, humans have plenty of experience with scienctific explanations eventually triumphing over supernatural explantions, that persisted from time immemorial, for observable phenomena. Therefore, it would be premature to jump to any conclusions about "proof" for God's existence.
One thing is pretty clear...if God does exist the unmistakeable evidence is not being volunteered.
