No mr unstoppable sex machine, he's saying that man is responsible for war and death (though not all pain, accidents disease). he's asking why should he believe in a god or gods that condone these things? Ignoring the the lack of physical evidence for a supreme being, on a philosophical level it's illogical that a an omnipotent being who apparently loves us all would let us suffer just so we could appreciate heaven? And if we are going to go to heaven and everything will be perfect for eternity, why do we need to through this reality, what's the point? Or is it that heaven is a crutch for people who've fallen on hard times in this realm and need something to believe in to cope with the reality of our basically futile existance?
The Vicar, yes sorry to hear about your mum too, that really is horrible for you and your family. My auntie had a a child with cerebral palsy, she turned to god, even as far as going to faith healers, unsurprisingly my cousin was never "cured" nearly 50 years later where has it got them?
Sit in a bath of baked beans for 5 years, run 100 marathons in a 100 days, do something to raise money for research, do the research yourself if you're clever enough, do something real. Best wishes.
