Help Me Out Fellow Atheists!
So I am later today going to be debating with a strong Christian friend of mine about his beliefs and he is going to try to prove to me that God does exist. We started last night but it was late when we started and he was using a book to help him out (it was called something along the lines of I Don't Have ENough Faight to be an Atheist or something of the like) while I was sitting there from everything I know from memory. He stumbles upon his words a lot, but that's fine.
But one of the arguments he might have me on (since I am not well educated in this field yet) is the one of the Big Bang. I use the thought of well, maybe the Universe is here for enternity and that it is matter and it cannot be created nor destroyed (forgot which law that is). But then he uses the second law of therodynamics and says that everything loses energy and so there has to be a beginning and end to the universe if it is running out of energy.
We were talking about the Flood as well and he was saying that most of the water was underground and there was very little above ground. Because of this, there was hardly any rain and the ground broke and flooded the earth or some shit....I don't know, it was kind of stupid but he was also saying there is evidence that there was flooding around the Earth.
I just need some help on arguments, questions that he wont be able to pick apart, and anything that might help.
