Could you please answer the question
I found some word in the dictionary that define a person who doesn't believe in God.
Here they are: atheist, infidel, pagan, freethinker.
I'm a little confused. I would like to know which of them is frequently used.
Can l use all of them in the following context?
for example :
"Do you believe in God?"
"No, I don't."
"Then you're an (atheist, infidel, pagan, freethinker)?"
