Both materialistic evolutionary theory and theistic (God-controlled) evolutionary theory claim that we are all descendants of fish.  Who could believe such a message? 

Only someone who wants to avoid God.

It gets worse.  Evolutionism teaches that we all came from rocks, violating known scientific laws to do so.  Evolutionists can't even show a workable way that we could have evolved.  They have now just gone to loopy logic and declaring evolution to be a fact.

Given the scientific facts that have been uncovered, a person would have to be willingly ignorant to believe such a thing. They would have to want very badly not to know about God's power and sovereignty, wouldn't they? They would have to just blind their eyes.

You and I know that God created us and God knows that we know.

There is a lot that you and I know about God just by looking at the creation. The Bible is very clear that God speaks to you through the Bible, and not only through the Bible. In Paul's letter to the Romans, it says that everything that can be known about God, and the Godhead (including Jesus and the Holy Ghost), is known to you and I through the things that He has created. When you look at the creation around you, God speaks to you through your conscience. That's why you know right from wrong. That is why you know that you are helpless to save yourself from your own sin. Though your conscience can lose its sensitivity when you continually ignore it, it is still there, and God speaks to you through it.

Only a fool would say in his heart there is no God.

God has made Himself very obvious in the things that He has created. And God knows that you know. He knows your thoughts even better than you do. You get confused with rationalized supposition and trying to hide your own sinful nature from others and from yourself. God is never confused. He is not impressed with phony arguments or human logic. It's between you and God, not anything else.

You can't fool God. No one can. He knows.
