Can you really know anything without God?

A certain user in various threads over the past week or two has posited the question:

Can you really validate your senses or reasoning without God?

Several posters have attempted to get this user to post this question as a new topic, but the user has thus far refused to do so.

I personally believe that use we really can validate our senses and reasoning without God.   One cannot even believe in God without this ability to use senses and reason–because how would you even know about God  and understand the concept of God without it?

I would like to get a mature discussion going on the topic. If we can.  Thank you!
