Preface It must first be said that this question is not asking for proof of God's existence. The answer has been edited for that reason. In Latin it was called "
evidere" which literally means "to look out." Evidence is something which we see that can help us form our conclusions. This is not a proof, which is facts that verify a conclusion.
This being said, you should read these evidences as merely evidence. I am not telling you to believe in my God, nor am I trying to dissuade you from your own belief system. However, these items can be considered evidences for the existence of God. Please be sure to read them with an open mind (and if you disagree, you can comment on the discussion page).
Biblical One must say that the Biblical evidence for God's existence is rather obvious. In most apologetic debate people will usually choose to disregard the Biblical evidence citing the Bible as not being a trustworthy resource. This, however, is a debate in itself. One which I will submit to you is a little harsh on behalf of the Bible. In truth we know that the Bible is the most printed, widely known, sold, and held book in the history of print. If we submit the Bible to the acid tests by which we hold other such historical documents (Josephus, Homer, etc.) we know that there are insurmountable copies in stella, papyrus, paper, and more. The historicity of other documents (such as Darnell's Gebel Tjauti Tablet,
e.3100's b.c.e.) are based on where the document was found, c-dating, and etc.
Natural The very beauty of the world we live in is evidence of our Creator. The calm and tranquility we feel when we're sitting next to a fresh water brook, watching a beautiful sunset, or feeling a pre-rain breeze blow past us is an evidence to the beauty which the world was created with. The absolute intricacy with which the universe works also speaks to the existence of God. The minute details by which protein is metabolized by DNA to form sequences and code which translate to who we are or even the balance of the universe in which nearly infinite planets and moons orbit nearly infinite stars speak of His presence. This is what has come to be known as Paley's Watchmaker analogy.
Philosophical Many philosophers have tried to reason the existence of God. Such as:
Thomas Aquinas--All objects have properties to greater or lesser extents.-If an object has a property to a lesser extent, then there exists an object which holds that property to a maximum degree.-There is an entity which has all properties to a maximum degree.-Therefore, God exists (being said object of maximum degree).
