I favor number 1, while recognizing that I do not understand the ultimate nature of God. As far as I am concerned there is only one Truth, and if we honestly seek it, science, religion and philosophy all have the possibility of bringing us to a point of confluence where that Truth is evident.

As for 1+1=2 - I'm not sure that is true. In a certain light 1+1=11. When we view reality through the lens of our human understanding we filter, group and categorize that information with inherent limits imposed by our nature, intellect, and senses. I'm betting that in the process we discard, or simply fail to notice, a lot of what is real. As a result a true understanding of the nature of the universe might only be achievable when the seemingly divergent lenses of science, philosophy and religion are unitedly focused on the question.
