Creationism is not science, but rather pseudo-science attacking science. Christians are unwilling to believe that they are intelligent animals, and fear that evolution will undermine their faith. Atheists should keep their minds open about Christianity, read the book of John and pray to Jesus, read Mere Christianity , etc. Many atheists have done these things, and often are quite knowledgeable about the Bible. This sets a very unfair standard, however, since the same things can not be said to Christians.
Christians expect atheists to consider their opinion, but refuse to reciprocate.
Prayer does not heal people, or we would see churches running the hospitals instead of doctors. The flood occurred, and Noah and his family took care of millions of animals. There are many questions surrounding this story that simply can't be explained. The earth is young. Geologists can show that there are rocks millions of years old, implying that the earth is that old unless God is trying to deceive us.
