I doubt I could convince anyone of anything, especially over an online forum. I believe most of what we believe is from persona experience and searching, not from the arguments of others - although we take them into account from time to time. I’m here for the same reasons you are. I will instead tell you why, and give you understanding of my position instead of the insistence that I am right.
I actually tried to believe in God for a long time… went to church, youth groups… even through college. I say tried because while I desperately wanted to believe, and tried to convince myself over and over, I never really did looking back. I’ve never seen a miracle, I’ve researched the origins of the bible, read most of it (although it’s been a long time), and looked for evidence of life after death. All I’ve found are insistence arguments, misconceptions, misunderstandings, and a lot of evidence that says this is it and there is nothing after this. In short… I’m agnostic by default, because I wasn’t able to substantiate my Christian upbringing with anything that I thought was satisfactory. I do still like the general Christian atmosphere and principals though, I just can’t agree with the extraordinary claims - those have been replaced, for me, by psychology, sociology, geology, paleontology, cosmology, biology, chemistry, physics, and my own experiences.
