But instead of wasting that money praying, imagine if it was used to cure all those problems forever? I don’t disagree that charity is a good thing, but you don’t need religion for that in the slightest. Praying does nothing, creating sustainable plant life for use in drought-affected countries is something that could make a real difference. You mention health care, that’s exactly where science has created massive leaps in the last few decades. Think about where we were compared to where we are.
I don’t know enough about theory to answer the Big Bang vs gravity question. However, I’d suggest that gravity as a force is likely to always have existed regardless, but I’d need to research that before being comfortable with it.
