There are two major problems with your request. First this isn't truly how science works. You can never "prove" something, you can only disprove something.
Please re-read what you told us. That it was "proven".
You find evidence that supports a theory, i.e. fits with what the theory predicts should. If you find something that doesn't fit, then the theory is modified to reflect the new evidence.
The problem with the evolutionary theory is that evidence is changed to fit the theory, not the other way around. Sometimes there comes 'evidence' so great that they have to change their theory, for example DNA, but only when there is absolutely no way to deny that evidence.
This is at it's core how science works. The theory of evolution is accepted because it is the best description of all the evidence we have.
Again, you're stretching things here. It might be "accepted" but just because something is "accepted" doesn't mean it's right. Take sin as a good example here. Sin is "accepted", yet it's not right.
I can't give you one piece of evidence and expect you to accept evolution. I myself wouldn't accept anything on only one piece of evidence. If you take the time to read up on the evidence that supports the theory of evolution you will find there is a lot of it.
If you take the time to read up on the "evidence" that contradicts evolution you would say the exact opposite. Evolution happens to be a topic of interest for me, so I've read a lot of the "evidence" that "scientists" (scientists is quoted because they rarely actually do any real science) try to claim.
What is laughable to me is that people are so fervent in their belief that the theory of evolution is accurate. You are arguing that theories change when evidence is found that can't be supported by the theory. As such, if you accept the theory as it is now, then you are accepting something that is open to change at any point, by the smallest, slightest bit of "evidence" that could completely disprove the "theory" or "scientific theory" as you're trying to argue.
You are also trusting a very elite, politically biased group of people to be honest in their work. A people who aren't known for their great moral code or for their honesty. You're trusting a group of people who's main source of income is in their grants, or private funding, as the work they are doing produces nothing of value. They aren't researching new products, or new technologies, they aren't doing anything that produces a good, and as such, their entire life depends on making sure their work is "important" enough to receive the grant money or other forms of funding.
