I wonder how one could go about doing such,,,

They're so much more fun. Here's a short list of things we could do if we brought back the Greek gods:
• Go to oracles.
• Go on quests.
• Fight monsters.
• Challenge gods to contests.
• Go to Hades and try to rescue dead loved ones.
• Dip babies in magic rivers, making them invulnerable.

Can we bring the Greek Gods back, please?
