Lil Angel, I try not to spend much time in threads that will go nowhere. However, for whatever reason, you seem like the kind of person that may have some curiosity or questioning.
StPatrick already has the basic argument I would provide, but it could be a bit more in depth.
We as humans like to form our theories on the universe on our own little perceptions. We anthropomorphize everything.
The universe does not work like our brains say it should - like we're used to on Earth. For example, we think of everything with a beginning and an end. On the small scale, things occupy multiple places at the same time. I can jump out of a plane before ever taking off. Or, I can jump out of a plane and take off at the exact same time. That's how things operate on the small scale. The beginning of the universe was a singularity, a very, very small thing therefore operating on the laws of quantum physics.
And history, I think we can agree that the you 10 seconds ago does not exist anymore. Only the you now does. But then where did the you 10 seconds ago go? Where did the you now come from? We generally operate on causation, but things don't need cause many times. Imagine a massive computer program designed to do a certain thing when in contact with certain things. When the program sees a dog, it will say "dog." The ways the computer will react are already there, just not expressed at the given time. Every expression the computer gives exists at the exact same time. It just appears differently according to what it is in contact with. That being said, the various stages of everything may very well exist all at the same time.
When you think of "God," you insert a mysterious, confusing, ultra complex thing that goes past cause, effect, and anything observable. Do you not? We just have to accept the fact that something out there in the universe is mysterious, confusing, complex, and beyond our comprehension at least at the moment. I completely agree with that last sentence. You inserted the word God out of - I'm guessing here - Americana. In America, God is the mystery behind the universe. I don't think we need to name it though. There is no reason to think it is "God." There is no reason to think there is a magic tooth fairy. Isn't it entirely reasonable to assume that there is more out there that we can't perceive - and that may include beings much more powerful than us - in the universe? You said so. I think so. Then, if we can't perceive it, or know what it is, then I say we cut out the word "God." I'll confess that it's probably not a tooth fairy if you'll confess it's not "God." We don't know - we can't see it!
All we know for sure is that the universe operates in funny, amazing, completely awesome ways that we don't understand - just like many natural things here on Earth. No one understands tornadoes fully. Why are there massive chunks of the inside of the planet spewing up in specific locations? That's confusing! But we don't say it's God. We don't say it's the tooth fairy. We say we don't know.
Now, in our confession that we are ignorant, we can make guesses. We need to test them though. Your guess is God. Well, we can go through so many different problems with that guess. God is a loving, caring creature. God created the universe, and his design is evident. He created galaxies for example. Galaxies are hundreds of billions of miles wide. They are beyond comprehension in their scale. God created them, put them in motion, and then...
And now many of them are colliding at millions of mph. Then we just simply look at the animal kingdom and how it relates to a blissful, loving, caring God... We have beautiful animals coexisting with each other peacefully, except we don't. They murder each other just to have enough food to live! In fact, many animals are designed to be extremely deadly. I took care of tarantulas for quite a few years, and they are not designed to coexist peacefully with anything!
The whole loving god as a designer thing just doesn't seem to work out. Maybe we can try other guesses though, and see if they work.
