what always gets me is... yeah, maybe the earth was formed by a huge explosion... but something had to be there to cause that explosion? another explosion? and so on...They can certaintly coexist if the person is willing to sacrifice many of creationism's cherished beliefs in light of scientific evidence. Unless you meant that God's hand in the scientific process is the process itself, then that is perfectly acceptable. You do not have to make a choice between God or science.
Might I suggest this link:

It covers the issue quite nicely.
