@Jasper10,
If you want to go the cognitive route then fine but consider all possibilities of that route......if we are only going to consider the biological reasonings then they will always...always cancel out ...hence why people arrive at the nihilistic view point...
where they go wrong is that they then deduce...
AND THEREFORE THERE IS NO GOD...
but they could also deduce...
AND THEREFORE THERE IS A GOD...
Why? because there is the possibility that it is only the biological reasonings that have cancelled themselves out....NOT the real YOU.
