There are so many ways to answer this question. I chose to answer it a bit different this time. Comment below with your answers!
Do aliens exist? If they did, would that affect Christianity?
Couldn't God have created a different world where children don't die? I also addressed this question in the blog, Why does God let a child die? Answer to the skeptic/atheist.
Before you answer, think about this question. Will straight people go to heaven?
No, but I think that 2 Corinthians 5:20 points to the fact that Christians should study worldviews.
