To feel bugs on your skin you only need the sensation of touch.
An itch is what you feel when a mosquito bit you.

Scratching has no positives, all you do is potentially hurt your skin, something that could potentially kill you in our natural environment.

The human species is intelligent which allows it to do that, but most animals can't.

But no-one said that evolution has to make sense, just that it happens.

This guy is so dumb he's actually saying "but touch can do that" well I guess pain is useless too? But you use that as an argument against why itching is useful so pain must be equally as useful as touch... something doesn't add up.
