Science is explicitly naturalistic. Science rejects the supernatural, not out of hostility to faith but because invoking the supernatural makes the answers too easy.
God is, by the definition of science, outside the scope of science.
Science is not alone in this. Accountancy also rejects divine intervention as an answer - the numbers have to work. In fact, accountancy is more strict in its rejection of divine intervention than science is. If you show a scientist a tree that grew in your back yard last night that has apples of pure gold on it, she'll work with you on it. If you tell an accountant that your balance is miraculously $1,000,000 more than the sum of your credits less your debits, she'll make the $1,000,000 go away.
Art is that way too - if I want to complete a painting, I must apply paint to a surface. I can't expect God to do it for me. And if He did, I would not be the artist.
A scientist who does not keep God out of his answers is like a builder who asks me to pray for God to keep me dry instead of building a decent roof. A good builder "rejects God", by building without trusting God to hold the walls up, in the same way a scientist "rejects God". It's called "doing your job" and most faiths say God (or whatever transcendant the faith observes) approves of it.
