God(s) and souls and spirits and 'hereafters'...etc...It's not something we are going to settle, are we? We all have our reasons and, at least partial explanations, for why we 'believe' or not.

The best we can do is to be true to ourselves and try to respect others trying to do the same.

I can relate jokes about God; I can debate theology when it's relevant; I can study the history and comparison of different religions; I can even explain the details of my own path from believing as a child to wondering as a student to doubting as an adult....but all I can do finally is to shrug and say I'm doing the best I can and hoping I leave this world having done my best to understand & make sense.
