Fishing seems to be the best variant. If you like you may spend a fortune on that, too, but generally some line, a rod and hooks is all you need to buy, the rest is having the necessity to waste some time. Maybe a permit. And sometimes there’s something fresh and even healthy to eat a result from it, too.
Your language is mixed up: You believe that God created the world. If you could prove it you would know, but you can’t. It would change your religion to a science.
Religion and science do work fine together, as long as the one doesn’t interfere with the other. Don’t try to prove your beliefs, don’t believe in knowledge that is unproven.
