Which things make Pagan a religion?

All Current Religions are based from the original Paganism.

Islam, for example, is based on the Pagan Religion of Moon Worship.

"Pagan" is a category, not a religion.

Jesus said that we can identify those who worship God in the right way. We do this by examining what they believe and what they do. He said: “By their fruits you will recognize them.” And he added: “Every good tree produces fine fruit.” (Matthew 7:16, 17) This doesn’t mean that those who worship God are perfect. But God’s servants always try to do what is right.

Our worship should be based on the Bible. The Bible says: “All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, so that the man of God may be fully competent, completely equipped for every good work.” (2 Timothy 3:16, 17) The apostle Paul wrote to Christians: “When you received God’s word, which you heard from us, you accepted it not as the word of men but, just as it truthfully is, as the word of God.” (1 Thessalonians 2:13) True worship is based only on God’s Word, the Bible. It is not based on human ideas, traditions, or anything else.

As I have said, Modern Paganism is a religious movement incorporating beliefs or practices from outside the main world religions, especially nature worship.

Synonyms for Pagan in the dictionary include: heathen, infidel, idolater, and idolatress.

"Pagan" is a generic term to describe every religion in human history except for a handful of mainstream modern religions.

More directly to your question, do you know how old you are in number of years or are you recognizing your birthdays? Because that's PAGAN!
