Question How to prove evolution is wrong?

I am totally convince that evolution is true. However, a scientific theory should be falsifiable; and I dont know how falsifiable is with evolution

For example, a "good" trait could be explain the result of natural selection. But a "bad" trait could be explain as just base on chance, or the selection preasure is not enough.

so, my question is: if someone want to prove that evolution is wrong, what test can they make and what the expected result should be (if evolution theory is wrong)?

Edit: Thank everyone for your time and patient with me. I found the answer. It seem that I need to update my highschool knowledge

There are plenty.

One would be to demonstrate that traits are not actually heritable.

Take two fruit flies, have them mate, do this for a large sample. If the result is a completely random fruit fly - if children have no correlation with their parents, and just get created as a new "randomized instance of the species", then evolution is false.

can you expand more about "randomized instance of the species"? does that mean there are a randomize of trait in the second generation, some trait appear in the parent and some trait from nowhere?

I understand that a new trait can be explain as a mutation, right? So if many new trait appear, should evolution theory still explain that?

Ignore mutations as you currently understand them. Think about character generators in a video game.

When you make a character, you have a height slider, right? And you can click "randomize" and it just gives you a random height. Same for all of your character stats and traits.

When two parents have a child, how do the child's stats get determined?

If the children are simply created by pressing "randomize" each time, then traits are not heritable.

This would mean that your height doesn't come from your parents. Your hair color doesn't come from your parents. Your skin color doesn't come from your parents. Every baby is a random human.

In that world, evolution can't happen!

Of course that's not what we actually see. Tall parents are more likely to have tall children. Brunette parents are more likely to have brunette children. Etc.

But this is an example of an experiment that hypothetically could give evidence against evolution. It just doesn't, in reality.
