I didn't believe in God a few years ago.
I've never met my bio-father. He didn't want anything to do with me (I cannot watch those 'families reunited' type programs - they turn me sick, and I'm always thinking
'yeah, right!' when the dad - who hasn't seen their kid since birth - is like 'Oh, I've thought about you every day!'

). I must be the spit of him because I look nothing like my mother! (of course, I also have suspicions that I was swopped at the hospital - I have dark green eyes and my mother has blue eyes!)
Also, I was bullied horribly when I was little, my mother is quite neurotic (I've grown up in a very schizophrenogenic environment - my BF is amazed that I haven't developed schizophrenia), and my ex physically attacked me a few times.
I didn't believe in anything.
I was asking the same questions as the OP. Why do bad things happen? If there is a God and He loves us all, why are there wars and people dying all over the world?
People would usually answer with, 'Because God gave us the ability to think and make decisions for ourselves', or the analogy of comparing God and human to parent and child (I can't remember exactly, but it was something about how, even though a parent loves their child and will do their best to direct them, the child will still be naughty and whatnot).
Now, I truly believe that there is a God. I'm not entirely sure what, exactly, changed my mind (it's probably a collection of things! - some of which I'd rather not discuss), but I do - and I feel so much lighter and better for it.

we're the only life on the planet that understands it's own eventual demise. why does that make us better than chimp? we share almost the identical DNA material, but they have no idea of their very existence and and ultimate death.
We also share about 96% of our genes with fish.
Life on Earth is quite similar throughout.
