Mutations disprove the theory of upward evolution

But the changes are random and not directed by an intelligence. So they are errors.

Nobody takes the bytes in a complied computer program and has the bits randomly changed and expects the program to work as well.

But only the beneficial 'errors' will be carried on to future generations. That's the whole point!

Not true if they don't kill or effect reproduction they can be passed on. Haemophelia, cystic fibrosis, MS etc survive despite being bad for the carrier.

However some changes which can bed bad can also be good, sicle cell anaemia confers some protection form malaria.
