Hello Sangha... What do you think? If yes, what makes it so? How do you define "religion"? Are some Buddhist traditions more "religions" than others? What makes it so?

Another question: I have prayer flags hanging over my front door, and someone asked me "what is this?" and I answered "Prayer flags"...
Then she asked "if you don't believe in God, who do you pray to?" Help me with this... what would you answer to a conservative Christian, with approx. 10th grade education... (my understanding would not make any sense to her).

Curious of your responses
with Gassho
