Re: spend it on space exploration/ Brain research.
You want to say 'nothing'. But you cannot prove that. But you want to research that. Well fine, then rule-out the possibilities scientifically. Don’t just 'decide'; "oh, I don't like the concept of 'God' because I can't wrap my brain around what that looks like, so I'll teach to ignore the potential"
Yeah. All those christian/muslim/jewish/etc. scientists who don't like the concept of god.
