How do you know you are a sentient creature with the ability to reason? Did you come to that conclusion using your reason? That's circular logic.I trust my ability to reason because I'm a sentient creature with the ability to reason; no god need figure into it, IMHO.
You believe your way, I'll believe my way.
On what basis can you trust your reason to come to that conclusion? Without an intelligent creator, you have absolutely NO REASON, epistemically, to trust your reason.
This fact is really at the heart of why atheism is foolish. Materialists think they are so much more intelligent than religious folks who rely on "faith" yet they have a totally blind faith in their logic without any grounds to do so.
