I agree with habiba, totally! And yes, there is proof that God exists. Some people just don't want to believe it, so they don't see the facts. Archeologists have proof that God made everything. I mean, look around you. How could the earth exist just because? Someone made it. And I believe God made it. Not some gases. And, New Forester, please, just listen. God didn't make us evil. He made us, and we get to choose our own lives, and our own future, and how we live it. God didn't make evil. I always thought of it as, Satan making evil. Because Satan is evil. And God isn't responsible for evil. We are.
And you do have a purpose in life. That's why God made you. But no one knows that purpose, except God. And I know it sounds like I'm preaching to you, 'cause, I sort of am.
'For God so loved that he gave him his only begotten son, that who ever believes in him, shall not perish, but have everlasting life.' John 3:16
Its up to you, if you want to believe that. It's your life. And it's up to you what your life is going to be like, after you die. And, bernardo, to me and others, there is a God.
Also, when people say stuff like there isn't a God, and the people who believe that there is a God. Just be prepared for some preaching and stuff like that. :)
