You need to think more about things? What exactly do you think more about? Answer my question at the end, what do you believe in? Do you believe in nothing? That we just appeared out of thin air? Surely you have to believe in something. Do you believe that god may or may not exist, we just don't know for sure? I still have yet to have someone answer my question on what they believe in, and tell me the main differences between being agnostic and being atheist for example. It seems to me atheists have absolutely nothing at all the think about. I would think the easy way out of explaining things is not explaining them at all, hence atheists. I don't believe in god or the bible too much though, I don't need nor care for an explanation regarding the universe or even life in general, I just have fun living it.
You know without religion there is still a universe to think about. The point of atheism is not to get out of explaining things, it's to explain them logically, using the scientific facts that we've found to this point. Science is what gave us the Big Bang theory. That is a logical beginning to the universe that makes sense to most people. That took years and years of study and research to come to. OTOH, just saying "Oh, God made the universe" takes all of 5 minutes to come up with.
All atheists don't believe the same thing, just as all religions don't. The only thing we have in common is the belief that there is no theistic god, such as the Abrahamic one. Personally I don't believe in any higher power that would be considered a god because I have no good proof of it.
The world is not nothing. The absence of a god doesn't mean there's nothing. We still have our world, planets, galaxies, the universe. I do believe that there is a chance that God exists. Anything is possible. The difference between my views and agnosticism is that I give God's existence much less chance of being right. Just as you can, I assume, admit the possibility that your god doesn't exist, I can admit that it might. A lot of Christians admit the possibility that they're wrong, but they're still Christians, not agnostics. I'm just the opposite.
And, as I said, atheism doesn't mean not explaining things, it just means explaining the same things religion does, but with real-world experience and research, not some "deus ex machina" (if you'll pardon the pun) kind of explanation that requires nothing more than a minute to learn.
