Most atheists feel the way they do because of propaganda from the deep state. If you can show them that they've been lied to about other things (space, wars, false flags, etc) you can possibly open up their minds to the fact that might have been lied to about science and God too.

I also like pointing out the arrogance of atheism. At the very least, a freethinker should refer to themselves as agnostic, not athiest. Atheists have faith there is no God the same way religions have faith there is a God. Agnostics admit there might not be a God, but that the truth is too complex to know for sure. We know barely anything about the universe, it's incomprehensibly vast. To assume that your feeble human mind has discovered the absolute truth about the forces at work in it is absurd arrogance.
