Here’s yet another video of a Christian who doesn’t understand science explaining why evolution must be false:

In case you’re wondering, there is a plausible evolutionary pathway for the bombardier beetle and you can read about it here.
More broadly, though, just because you can’t fathom how nature evolved a particular mechanism doesn’t mean the explanation isn’t out there.
Ignorance isn’t proof that science is wrong.
