The first issue that I have with Christianity is if Jesus Christ was the son of God then why didn't he tell the people during his time that the Earth was round and that it orbited the sun? It isn't unreasonable to expect that the son of the being who supposedly created the solar system would have known that. Why didn't Jesus tell people that there were huge continents on the other side of the planet that were inhabited by tens of thousands of people? Why didn't Jesus tell his followers about the things that make people sick? Wasn't healing supposed to be one of his things? Well, why didn't he tell people about viruses and bacteria? The reason, of course, is because Jesus obviously knew little about the natural world.
I'm sorry, folks, but that would've been a complete and total impossibility for someone who was really the son of the Creator. And to drive that point home even further, keep in mind that Christian scholars even claim that, according to certain passages in the Bible, Jesus and God were actually one in the same. God was Jesus. Jesus was God. The bottom line is that there's certain things that Jesus Christ should've known if he was really who the Christians say he was, but he didn't.
