Sorry Icey, I agree with you on lots of things but not that. Sure, there's an awful lot we don't understand. but there's simply no evidence or even logic that we exist as anything but biological entities, and any talk about spirits or soul's is just human's making up fairy stories.
Best regards to you also -
That's not true, there is plenty of evidence that we are not simply mechanical biological entities, but you have to be eclectic in your search and the time to look at a very broad spectrum of evidence. You mention logic, I assume you mean syllogystic logic is a closed information system and as such renders no new information and is flawed for a number of reasons including the fact that it's conclusions are often drawn from assumed premises.
In science the big question is Consciousness, and what it actually is because science can't bridge the gap between the sensory input of the material body and the immaterial nature of consciousness, let alone the evanescent nature of thoughts. Scientific materialist believe (like youself) in the primacy of the material world, with consciousness as a secondary experience. However the latest scientific thinking has made a paradigm shift and is at last starting to move in the right direction and now the possibility is being considered of counciousness as the primary experience and the physical world secondary. Put another way, to experience the world you must first be conscious. What that means is that all experience is consiousness, and the material world, as real as it seems is a construct of that consciousness. This may be new to science but the theory is actually over 2000 years old along with the proof, you just need to know where to look.
Once consciousness is understood to be the primary experience then everything changes. The problem with most people's understanding of things is that it takes binary form, either something is or it isn't, Yes/No 1/0 everything is black or white, but the real world isn't like that. If consciousness is the primary experience and the physical world a construct of that consciousness then physicality is both real in the immediate experiential sense, and but not real in the sense that it is a construct of consciousness. In real terms this means the world is not what you think it is and all your most cherished beliefs are based on a failed understanding of the nature of your existence. So your understanding not just about religion and whether or not God exists but everything is incorrect.
