I don't think anyone can really say they understand all of God's actions and thinking. God has also gave human the wisdom to devise and allocate medicine to cure AIDS.
Believing in God, I reckon, needs a lot of faith - to believe something that you can't comprehend. The God I believe in doesn't want to force people into believing that He exists. He wants to give people a choice to believe what they want and find out for themselves. That's why, in my opinion, I think He doesn't give us much really solid, convincing, obvious facts and evidences that He exists. Although I cannot explain everything about God, I still believe He exists because also of all the supernatural things I've heard, seen and experienced.
LOL i think by 4 billion years we won't be here to witness what happens XD
Brendan, how do you think that the universe exist without being created then? How does something just have always existed? Isn't it logical that there must have been a starting point?
