When I believed in a god, I couldn't imagine not believing in a god. I thought life would be sterile and pointless without a god. Then one day, I looked up and realized, I no longer believed there was a god. It didn't feel stark and empty, but just the opposite. It was exciting, and felt like my brain was working and making connections that I had been preventing. It felt liberating. Life in that moment became more precious than ever. I was no longer living for the future, but was free to enjoy the right now. No more time wasted. No more dilemma. My anxiety dropped to an all-time low.
I'm just saying, that when we believe in a god, it's hard to imagine or ever understand what it would be like to be an atheist. Atheism seems pointless and void of all hope. But once I stepped over here (and like Cofty said, not a choice. I was never seeking to become an atheist, but the evidence piled up and it had to be dealt with) I realized that life was still wonderful and even more wonderful.
