Don't feel so badly. Those jokers are as ignorant of everything else as they are of the existence of God. In fact, they can't even understand that God exists for starters, even when someone shows the proofs for God's existence like these:

Let them go. They, the dead, will bury each other, and people who follow God will never have to put up with them again.

Machine-like nature of the universe.
     All around us, in nature and the universe we see machine-like operations. These operations are extremely complex inside life and the cells. Machines have makers.

Machine usage is in progression.
     Animals use simple machines. Some primates (apes, chimps, monkeys) use rocks and sticks to work their food. The leverage they provide with the rocks and sticks is machine use.
     People use simple machines. People make and use complex machines. All machines that people and animals make and use come from examples of machine operations in the universe.
     The progression is that, as the machines that people make and use are far more advanced than the ones that animals make and use, so are the machines that exist in nature far more advanced than the ones that people make and use. The advanced machines of the universe have an advanced Maker - God. Machines have makers.
