Is it normal that a girl wants me to do this ?

My new best friend said she wants to have a baby with her. I've only known her for a week. I love her as a friend. She thinks we'll be the perfect parents if we have a kid together. She said she wants to do it tomorrow night when she sees me again. I don't even know her that well. I don't know how to tell her I'm not ready for kids I'm not ready to be a dad. I'm afraid I'll hurt her feelings if I say it to her. She thinks I'll be the perfect father. She just text me and asked her when we get to the church tomorrow if I'll take her in the bathroom so we can have sex so she could have a baby. It seems really wrong especailly to do in church. I'm about ready to call and tell her we shouldn't do it. I love her I think she's a really sweet girl but I don't want kids yet I don't know how to tell her without upsetting her. She also seems young to want kids anyway she's 6 years younger than me. I hate to make a girl cry but I don't think it's right to do this to her. Is it normal that she wants me to get her pregnant ? How can I comfort her if she cries when I tell her no ?
