A couple of words about Christianity:
We are born without the knowledge of the concept of God. We learn about God only from our peers. Atheism is the continuation of one's inherent lack of belief concerning Gods. Theism implies that throughout the lifespan of a person, some event or experience changed his state of God-belief, going from not even knowing what a God is, to believing in him fully. Atheism implies that, literally, the person has found no reason to believe in God. Due to these facts alone, the burden of proof is always on the theist, since the neutral state is not having a belief concerning God, which is atheism (weak).
As for looking at the sky to see evidence of God, that is simply idiotic, since you are implying a non-cogent argument: the world is a cool place, therefore God exists. Do you realize that the sky consists of miles of gaseous molecules? Did you know that past it is a vast and great stretch of emptiness in every direction, with an occasional stellar body showing itself every once in a while? Of course you do, thanks to science. So far, every answer that we have come up with has been done with science. How many answers have we come up with through theology? Theists propose the God of the gaps argument, claiming that just because we do not yet know something, we will never know it, and further, that a strangely inconsistent deity is responsible for all things we do not know. Naturally, they display no evidence to show just how and why this deity is responsible, and, better yet, how they came up with this knowledge, but I guess that's too much to ask. But the intellectual dishonesty gets worse! Certain theists are not content with not yet having an answer: if something cannot be answered, they must fill in one! Their worldviews do not allow them not to be at least pluriscient. When scientists discover a solution to a question posed earlier, theists simply move on to another area of knowledge that the scientific community has not yet fully explored.
Realize that adding "God did it" does not add any new knowledge. Furthermore, for the creationists among us, questioning evolution is trendy and all, but please, come up with a better theory, and then we'll consider it.
