I'm not certain that a Creator exists, but in view of the available evidence, it seems like a not-unreasonable bet -- depending of course on what the stakes are. (The degree of confidence you want in any Proposition X will depend in part on what happens if you're wrong.)
And over the long term, following the Summary of the Law that Jesus stressed -- which can be recast as, 1) face the facts, and 2) seek the best for others as you do for yourself -- appears to be adaptive behavior for individuals and cultures.
The Summary of the Law is by no means uniquely Christian, incidentally; it's Jewish (hey, Jesus was nothing if not a good Jew), and also finds expression in other faiths.
