I'm not sure what this has to do with God, Theland, but I believe we have more than five senses. Although it isn't always dependable, I think instinct can be regarded as sixth sense. I also believe some people are able to detect aspects of what we, in my opinion, erroneously, term 'the supernatural', and that could be regarded as a seventh sense. (Starman, I just know you're gonna hate that bit - but, hey ho, that's what my experience of life has led me to conclude).
what if God exists in the parts of the universe that you don't understand?
What if he does? We have no indication of that, and therefore until we have some evidence to suggest that this may be the case, then there is no reason to believe that he does.
Or what if He exists in the bit that you understand as well, but you simply didn't recognise Him.
If he existed in the bit that we recognise, then once we'd spotted something unfamiliar, we would investigate. Since there cannot be anything within the sphere of our knowledge that we don't recognise, then currently we can only conclude that he isn't there.
Basically, Theland, what you're saying is we should be seeking something we have no evidence for, and therefore no rational reason to look for. Where's the sense in that?
