Hi Elqayyam,
Welcome to the site and the forum.
As you can see there are a wide range of topics and discussions on the site so feel free to peruse and put your 10cents worth in on any of the topics.
Many of the posters on this site are atheists/agnostics but we welcome discussions and participation from believers of all stripes.
As you will also see, many of us are highly sceptical of all religions and religious claims, and while we are nice people, you can be assured that discussions will be 'lively', so bring your best cards to the table.
Have fun!
Adey
