JIA, if there is a multiverse - like M theory suggests - than the creation of the universe is a very small part of creation. The cycle goes on and on. It never ends. Even if God were scientifically validated, with everything written on the necessity of a God by scholarly and educated individuals like Patrick Mead, in the end - even the evidence for God is subject to scientific scrutiny.
I have yet to make a life-changing decision, and I just don't know if I should or shouldn't. But I do know that if I do become a true Disciple, it won't be about the scientific facts, it will be about whether or not the choice, and the sacrifices entailed, are worth the risk of me being wrong about this one truth.
Faith is not necessarily following blindly, but it is following the incomprehensible plan of God. To know God through science is to know everything there ever will be to know, for as long as there is the unknown science says God is potentially falsifiable. We are not omniscient.
