Religion

My friend and I had a discussion about religion and which religion is right. Well, what do you believe?
I believe in God, the Father the Almighty. But some believe in Buddha, Allah, or many gods and goddesses. But who is right? Because all believers think that they're religion is correct. I like to think that my God is the only, but what if I was wrong? So my theory for the correct religion is that all religions are the same....except they were interpreted differently. We all have different cultures, so naturally we interpret things differently. So who is to say that all religions aren't just different forms of the same people? They have different names and images, but the theory is believable. So think about your religion....
