Quite so. For one thing, we didn't toss a coin to see who would argue for which position. Well, I didn't. If you did, that might explain where you went wrong.
A second thing: when you debate issues of science, data (evidence) is what counts. Debating tricks/techniques/tactics might appear to carry the issue (such as creationists and their gish gallop, etc.) but those things do not hold up for long in the face of accumulated evidence, which is the forte of science.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
