I'm sure you've study a little history on the Ancient Greek Gods. It's actually a fun study to look into and it definitely gives you an overview on ancient societies and ancient history of some of the cultures of the world. There is so much history when it comes to mankind that to study it all could take a lifetime. Just imagine living 1,000 years ago, or even in the days of Christ.
I love to read the Bible which shares accounts clear back to creation in the book of Genesis when the Lord God formed man from the dust of the earth. We all know the story of Adam and Eve. The Bible is filled with history, accounts, life and matters that pertain to eternal life. Let me encourage you to add the Bible to your studies daily. For within the scriptures are some of the most important things you will ever read.
Blessings, and remember God loved the world so much that He gave His only begotten Son Jesus to die for the sins of the world.
