This is where I interject & mention this.
https://en.wikipedia.org/wiki/Opportunity_cost
People don't want to feel like they wasted time & resources over something that doesn't exist.
Religion can just be relegated to a construct for social activities. There's so many of them which sprung up independently. People should really ponder whether they have accounted some belief for interplanetary travel.
If you bring up opportunity cost, I think it's also worth mentioning Pascal's wager[0]. I don't believe in this argument, but it's an interesting point to consider.
