God is an eternal being and whatever is eternal, transcends space and time.

Can you imagine having a book without an Author or a building without a Builder or a painting without an Artist? Authors, Builders, and Artists are implied to exist because of the existence of their creations. God either exists or He doesn't exist. There are good arguments in favor of God's existence.

Evil is not a thing or an entity, it is the absence of good. It is a corruption of something good; such as when a beautiful car gets marred  by rust. There is natural evil such as tornados, earthquakes, drought, etc. and there is moral evil such as infidelity in a marriage, serial killers, and mass murders.

Is God the uncaused creator of the universe or is the universe uncaused and eternal? Has the universe always existed? Before the 20th century there wasn't any way to prove which theory was correct. .
