First of all: @Putin: No, it implies that we could put other things before God in our life, making 'gods' of a sort.
Now, evidence time: I guess most atheists agree that Jesus was a real person, even if he wasn't God. Now, I assume you know there were many prophecies made in the old testament about Jesus. Some won't come true until Jesus returns, some you atheists don't believe because they involve Jesus' miracles or his rising from the dead. But there are plenty that history agrees definitely took place. Now, I once heard that the odds of all the prophecies about Jesus coming true for one person is about 1 in i think 10^63. Now I have no idea how this was calculated and it was likely pulled out of someone's ass. But considering that there were hundreds of prophecies about Jesus, I'm sure the odds are very slim. Now, I'm not sure how many of those hundreds of prophecies even atheists agree happened with Jesus (i.e. ones that don't involve miracles or rising from the dead). If any atheists here know, could you please tell me? Anyway, the # is probably 1 or 2 hundred. And I'm sure the odds of those prophecies coming true for one man are extremely slim as well. So yeah, that's my first bit of evidence, and it is admittedly the weakest. But I have more.
My second bit of evidence is this: Doesn't the creation of the universe violate the Law of Conservation of Energy. How the hell can it's matter just 'appear'? Doesn't it need a supernatural creator who can break laws of physics, and is not made of matter, to create it? What other possibility is there, that doesn't break a law of physics?
My third bit of evidence is this: If Jesus didn't rise from the dead, where is his body? And if you say that his disciples took it, I hope you realize that his tomb was guarded by a bunch of TRAINED Roman guards. It would be pretty damn hard to steal it away from them. (I believe that the official report is that they were asleep when it was stolen, but if they were asleep, then how could they know it was stolen? And also, there was a HUGE stone in front of the tomb. I think moving that stone would have woken them up). Also, all of Jesus' disciples dies HORROBLE deaths for being Christians. If they actually stole the body and knew that Christianity wasn't true, don't you think they would have stopped the hoax to avoid being killed? But they didn't.
There are also a lot of little evidences here and there for God's existing. All circumstantial, but still evidence. In fact, there are so many, I don't think I could post them all here. But a simple google search of "evidence of God's existance" should turn up numerous lists.
