I don't know how the Universe began, but I can see that it exists here and now, and I am in it.
Just because I can't tell you how it began, does NOT mean I have to accept "God did it" as an answer. That is just an appeal to the "God of the Gaps".
However, I can't understand most high level science anyway, but I think the scientific method is a better method for investigating the natural world, than a two thousand year old document that was written by a bunch of primitive goat herders, and has been transalated from several languages and cultures.
I don't understand how most medicine works, but if I suspected I had cancer, I would not go to a Shaman or a priest for a diagnoses, I would go to a DOCTOR.
If my car stopped running, I wouldn't take it to a church, I would take it to a mechanic.
Theology can answer questions about the MEANING of life, I look to science to explain the mechanics of life.
