Atheists, tell me, a Roman Catholic: why should I become an atheist?

People often take that to mean "mankind", and it does say that in Genesis 1, but if you recall the story of creation from Genesis 2, God only actually "created" Adam, the man.  So when the Bible says that God made man in his own image, it is not talking about mankind, it is talking about a literal man.  Eve was an afterthought, not "created" at all, but formed from a piece of man.

Remember that there are two creation accounts. In Genesis 1:27 it states "So God created mankind in his own image, in the image of God he created them; male and female he created them." God then goes on to address both of them when he offers his blessing and grants them dominion over the whole planet. It is the second account that separates them and places the man above the woman by making her a companion who was created to fulfill a need (Genesis 2:18-- The Lord God said, “It is not good for the man to be alone. I will make a helper suitable for him.”).

It seems as if --depending on the writer and the needs of the particular story-- women are treated as ornaments most of the time in those early stories, until the law given to Moses turns them into property (Exodus 20:17 “You shall not covet your neighbor’s house. You shall not covet your neighbor’s wife, or his male or female servant, his ox or donkey, or anything that belongs to your neighbor.”). And of course, in spite of the belief that marriage is between one man and one woman and that any exception to this is fornication or adultery, later stories have the men marrying multiple women and keeping concubines because LOL CULTURE.
