“Now after this life I can't say what will happen and neither can you.”
Actually, if Materialism and Naturalism were not just lies, then this would be a true statement because there would be no God Who reveals what happens after this life.

We do know a lot about what will happen after this life because God has revealed it. The Atheists also know about this. For more about this, look here.
