Philosophy and Proofs
Atheism includes any philosophy which claims that no God or gods exist, including any rational or reasoning creator of the universe.
Christianity is the philosophy that claims that Jesus of Nazareth is the Son of God and Jewish Messiah (or Christ); that he was crucified, died and was buried, and rose again three days later; that his death was an atoning sacrifice for the sins of his followers; and that placing one's trust in Jesus is how any sinful person can be forgiven and made righteous before their creator.
Empiricism describes any philosophy which claims that all knowledge originates in experience, denying the validity of both deductive reasoning and divine revelation.
Islam refers to the specific philosophy of the Muslims, a monotheistic and unitarian belief system declared by Muhammad in 610 AD and described in the book known as the Qur'an.
Monotheism refers to any philosophy which claims that there is only one supreme creator of the universe.
Open theism refers to any philosophy which claims that there is a supreme creator of the universe who does not foreknow the outcome of human choices.
Pantheism denotes any philosophy which claims that god and the universe are identical.
Polytheism refers to any philosophy which claims that there are multiple supreme creators of the universe.
Rationalism describes any philosophy that claims that beliefs and opinions should always be logical, deductive conclusions rather than being based on experience, observations, religious teachings, or divine revelation.
Theism includes any philosophy which claims that some kind of God or gods exist.
Trinitarianism is the philosophy that there is only one God in terms of essence or being; and that the one God is revealed through three eternally distinct persons, specifically, the Father, the Son (Jesus of Nazareth), and the Holy Spirit. Trinitarianism is unique to Christianity.
Unitarianism refers to any philosophy which claims that divine sovereignty is not shared in any way.

"Is rape acceptable or unacceptable in your worldview and why? What do your scriptures (if any) say?"
The God of the Bible condemns rape, and therefore, so do Christians. Beginning in the book of Genesis, we read about God's condemnation of rape: Genesis 34:2-7 (NASB) When Shechem the son of Hamor the Hivite, the prince of the land, saw her, he took her and lay with her by force. He was deeply attracted to Dinah the daughter of Jacob, and he loved the girl and spoke tenderly to her. So Shechem spoke to his father Hamor, saying, "Get me this young girl for a wife.
"How is God any different than Santa Claus?"
This is sort of an odd question as there are so many very obvious differences. For example, Santa wears a red hat, whereas God doesn't have a physical head to put a hat onto. I don't know of any religion or worldview that claims that God climbs in and out of chimneys, either. There is, in this question, an implicit attack on theism. However, it is quite possibly one of the silliest attacks on theism I have ever encountered, and I encounter it rather frequently.
"Has God always existed and always will? If so, how did God design the universe if nothing existed to guide him and nothing existed for him to think about."
I don't think I completely understand your question. The question itself seems to presuppose some things that are not accurate, and so I'm not really sure how to answer it. If your basic question is "how did God design the universe?" then I can honestly tell you that I have no idea -- God didn't specifically tell us how He did it and I have never designed a universe myself, so I wouldn't know the first thing about it.
